Mercury toxicity due to the smelting of placer gold recovered by mercury amalgam. (1/710)

A 19-year-old man developed tremor in both hands and fatigue after starting work at a placer gold mine where he was exposed to mercury-gold amalgam. Examination revealed an intention tremor, dysdiadochokinesis and mild rigidity. The 24-h urinary mercury concentration reached a peak of 715 nmol/l (143 ug/l) shortly before the clinical examination, after which he was removed from working in the gold room [Mercury No. Adverse Effect Level: 250 nmol/l (50 ug/l)]. On review 7 weeks later his tremor had almost resolved and the dysdiadochokinesis and rigidity had gone. The 24-h urinary mercury concentration had fallen to 160 nmol/l (32 ug/l). The principal exposure to mercury was considered to be the smelting of retorted gold with previously unrecognized residual mercury in it. The peak air concentration of mercury vapour during gold smelting was 0.533 mg/m3 (Mercury Vapour ACGIH TLV: 0.05 mg/m3 TWA). Several engineering and procedural controls were instituted. This episode occurred at another mine site, unrelated to Mount Isa Mines Limited.  (+info)

Carbon disulphide absorption during xanthate reagent mixing in a gold mine concentrator. (2/710)

A xanthate reagent mixer at a gold mine concentrator was exposed to carbon disulphide by extensive skin contamination with xanthate powder and solution during the reagent mixing process. Absorption of carbon disulphide was confirmed by the detection of urinary 2-thiothiazolidine-4-carboxylic acid (TTCA). Drager colorimetric tube testing during subsequent mixing recorded a maximum concentration of at least 60 ppm carbon disulphide. An illness consisting of predominantly gastrointestinal symptoms began 20 h after the exposure. Although this may have been due to carbon disulphide toxicity this is by no means certain. The need for engineering controls, impervious protective clothing and full-face respirators with particulate and organic vapour cartridges is discussed. This episode occurred at another mine site, unrelated to Mount Isa Mines Limited.  (+info)

A risk assessment for exposure to grunerite asbestos (amosite) in an iron ore mine. (3/710)

The potential for health risks to humans exposed to the asbestos minerals continues to be a public health concern. Although the production and use of the commercial amphibole asbestos minerals-grunerite (amosite) and riebeckite (crocidolite)-have been almost completely eliminated from world commerce, special opportunities for potentially significant exposures remain. Commercially viable deposits of grunerite asbestos are very rare, but it can occur as a gangue mineral in a limited part of a mine otherwise thought asbestos-free. This report describes such a situation, in which a very localized seam of grunerite asbestos was identified in an iron ore mine. The geological occurrence of the seam in the ore body is described, as well as the mineralogical character of the grunerite asbestos. The most relevant epidemiological studies of workers exposed to grunerite asbestos are used to gauge the hazards associated with the inhalation of this fibrous mineral. Both analytical transmission electron microscopy and phase-contrast optical microscopy were used to quantify the fibers present in the air during mining in the area with outcroppings of grunerite asbestos. Analytical transmission electron microscopy and continuous-scan x-ray diffraction were used to determine the type of asbestos fiber present. Knowing the level of the miner's exposures, we carried out a risk assessment by using a model developed for the Environmental Protection Agency.  (+info)

Leptospirosis and Ebola virus infection in five gold-panning villages in northeastern Gabon. (4/710)

An exhaustive epidemiologic and serologic survey was carried out in five gold-panning villages situated in northeastern Gabon to estimate the degree of exposure of to leptospirosis and Ebola virus. The seroprevalence was 15.7% for leptospirosis and 10.2% for Ebola virus. Sixty years after the last seroepidemiologic survey of leptospirosis in Gabon, this study demonstrates the persistence of this infection among the endemic population and the need to consider it as a potential cause of hemorrhagic fever in Gabon. There was no significant statistical correlation between the serologic status of populations exposed to both infectious agents, indicating the lack of common risk factors for these diseases.  (+info)

Cellular responses to Plasmodium falciparum major surface antigens and their relationship to human activities associated with malaria transmission. (5/710)

In Brazil, two types of activities have led to the worsening of malarial transmission in the Amazon region: prospecting/mining and agricultural settlements. In the present study, we analyze the cellular response of 52 of these individuals (14 gold-miners and 38 farmers) living within the same endemic area. Two Plasmodium falciparum major surface antigens (recombinant proteins) were used for cellular proliferative assays: circumsporozoite protein and merozoite surface protein-1. The frequency of these cellular responses were significantly higher among the miners (57-64%) than the farmers (10-20%) when either recombinant protein was used. Our data suggest that a higher exposure to malaria of the gold-miners contributed to their higher in vitro cellular response compared with the farmers. These findings point the way to further studies evaluating the influence of risk factors associated with the life styles of different social groups and the immune responses to these antigens.  (+info)

Clinical and laboratory manifestations of systemic sclerosis (scleroderma) in Black South Africans. (6/710)

A retrospective study of systemic sclerosis (SSc) in Blacks attending a tertiary hospital on the Witwatersrand, South Africa, was undertaken. The female:male ratio of the 63 patients was 4.6:1 and the mean age of onset of SSc was 36.1 yr. Four of the 11 males were ex-goldminers and nine females resided close to goldmines. Forty-one patients had diffuse cutaneous SSc (dcSSc), 18 had limited cutaneous SSc (lcSSc) and four were unclassified. Overall, 56% had pulmonary fibrosis, 37% had myositis and 98% were antinuclear antibody (ANA) positive, with a notable absence of anti-centromere antibodies. Subset comparisons showed myositis and a reduced forced vital capacity to be significantly more common with dcSSc than lcSSc. The only significant sex differences were that arthralgia/arthritis was more common in women, while calcinosis occurred more frequently in men. Seven of the eight known deaths occurred in patients with dcSSc. These findings, particularly the age of disease onset, predominance of the dcSSc subset, inflammatory features of myositis and a raised erythrocyte sedimentation rate, and absence of anti-centromere antibodies, are similar to those reported previously in African-Americans.  (+info)

Radionuclides in the lichen-caribou-human food chain near uranium mining operations in northern Saskatchewan, Canada. (7/710)

The richest uranium ore bodies ever discovered (Cigar Lake and McArthur River) are presently under development in northeastern Saskatchewan. This subarctic region is also home to several operating uranium mines and aboriginal communities, partly dependent upon caribou for subsistence. Because of concerns over mining impacts and the efficient transfer of airborne radionuclides through the lichen-caribou-human food chain, radionuclides were analyzed in tissues from 18 barren-ground caribou (Rangifer tarandus groenlandicus). Radionuclides included uranium (U), radium (226Ra), lead (210Pb), and polonium (210Po) from the uranium decay series; the fission product (137Cs) from fallout; and naturally occurring potassium (40K). Natural background radiation doses average 2-4 mSv/year from cosmic rays, external gamma rays, radon inhalation, and ingestion of food items. The ingestion of 210Po and 137Cs when caribou are consumed adds to these background doses. The dose increment was 0.85 mSv/year for adults who consumed 100 g of caribou meat per day and up to 1.7 mSv/year if one liver and 10 kidneys per year were also consumed. We discuss the cancer risk from these doses. Concentration ratios (CRs), relating caribou tissues to lichens or rumen (stomach) contents, were calculated to estimate food chain transfer. The CRs for caribou muscle ranged from 1 to 16% for U, 6 to 25% for 226Ra, 1 to 2% for 210Pb, 6 to 26% for 210Po, 260 to 370% for 137Cs, and 76 to 130% for 40K, with 137Cs biomagnifying by a factor of 3-4. These CRs are useful in predicting caribou meat concentrations from the lichens, measured in monitoring programs, for the future evaluation of uranium mining impacts on this critical food chain.  (+info)

Methylmercury neurotoxicity in Amazonian children downstream from gold mining. (8/710)

In widespread informal gold mining in the Amazon Basin, mercury is used to capture the gold particles as amalgam. Releases of mercury to the environment have resulted in the contamination of freshwater fish with methylmercury. In four comparable Amazonian communities, we examined 351 of 420 eligible children between 7 and 12 years of age. In three Tapajos villages with the highest exposures, more than 80% of 246 children had hair-mercury concentrations above 10 microg/g, a limit above which adverse effects on brain development are likely to occur. Neuropsychological tests of motor function, attention, and visuospatial performance showed decrements associated with the hair-mercury concentrations. Especially on the Santa Ana form board and the Stanford-Binet copying tests, similar associations were also apparent in the 105 children from the village with the lowest exposures, where all but two children had hair-mercury concentrations below 10 microg/g. Although average exposure levels may not have changed during recent years, prenatal exposure levels are unknown, and exact dose relationships cannot be generated from this cross-sectional study. However, the current mercury pollution seems sufficiently severe to cause adverse effects on brain development.  (+info)

OBJECTIVES: To identify risk factors for small-for-gestational age (SGA) for counties in central Appalachian states (Kentucky (KY), Tennessee (TN), Virginia (VA), and West Virginia (WV)) with varied coal mining activities. MATERIAL AND METHODS: Live birth certificate files (1990-2002) were used for obtaining SGA prevalence rates for mothers based on the coal mining activities of their counties of residence, mountain-top mining (MTM) activities, underground mining activities but no mountain-top mining activity (non-MTM), or having no mining activities (non-mining). Co-variable information, including maternal tobacco use, was also obtained from the live birth certificate. Adjusted odds ratios were obtained using multivariable logistic regression comparing SGA prevalence rates for counties with coal mining activities to those without coal mining activities and comparing SGA prevalence rates for counties with coal mining activities for those with and without mountain-top mining activities. Comparisons were

As conflicts with local communities are a problem for oil, gas and mining companies around the world, a new report from international relief and development organization Oxfam finds that the number of mining companies with commitments to Free, Prior and Informed Consent (FPIC) has almost tripled since 2012. While positive, this trend masks a number of weaknesses related to protecting the rights of local communities and indigenous people near large-scale projects.. The 2015 Community Consent Index examined policies regarding community rights and community engagement of 38 oil, gas, and mining companies, including ExxonMobil, Chevron, Shell, Anglo American, CNOOC, Petrobras, BHP Billiton, RioTinto, Total, Vale, and BG Group, among others. The Index found that extractive industry companies are increasingly seeing the relevance of FPIC to their operations, but the oil and gas sector is lagging and companies are struggling to implement FPIC as clearly defined by international bodies and law.. As ...
The relationship between environmental exposure and health outcomes is complex, multidirectional and dynamic. Therefore, we need an understanding of these linkages for effective health risk communication. Despite the severe health hazards, artisanal gold mining is widespread globally, with an estimated 30 million people engaged in it. In this study, the relationships between artisanal gold miners knowledge of environmental and health effects of Hg and compositional, contextual and occupational factors were assessed using generalized linear models (negative log-log regression). A cross-sectional survey in three urban gold mining hubs in Ghana (Prestea, Tarkwa and Damang), was carried out among 588 (482 male and 106 female) artisanal gold miners. The results showed that 89% of artisanal gold miners had very low to low levels of knowledge whereas 11% had moderate to very high levels of knowledge of deleterious health effects of Hg. Also, individuals who perceived their health-related work conditions to be
Illegal artisanal gold mining using mercury amalgamation is poisoning people and the ecosystem in the Amazon rain forest. By taking the technique of direct mercury analysis to a remote, field-based laboratory, the team of Professor Luis Fernandez is measuring the extent of the contamination in a wide variety of samples, including soil, fish, air and human hair.
When Goa mining delegation met Prime Minister and asked for help, the PM said, while environmental concerns should be sincerely addressed, all should remember that poverty is the greatest polluter. Union Finance Minister P. Chidambaram statement on iron ore mining to find a way to export iron ore and restart iron ore mining is already more than 3 months old.. Union Minister of Commerce and Industry, Anand Sharma too spoke on removing the ban by stating that we dont want ban to continue and all mining activities are not illegal and stressed upon iron ore export. But these statements have given no reprieve to the iron miners in Goa and Karnataka. Their vows do not seem to end..

Mining legacies are often dominated by large waste facilities and their associated environmental impacts. The most serious environmental problem associated with mine waste is heavy metals and acid leakage through a phenomenon called acid mine drainage (AMD). Interestingly, the toxicity of this leakage is partly due to the presence of valuable metals in the waste stream as a result of a diversity of factors influencing mining operations. A more preventive and recovery-oriented approach to waste management, integrated into mine planning and operations, could be both economically attractive and environmentally beneficial since it would: mitigate environmental impacts related to mine waste disposal (and consequently reduce the remediation costs); and increase the resource recovery at the mine site level. The authors argue that eco-efficiency and resilience (and the resulting increase in a mines lifetime) are both critical-yet overlooked-characteristics of sustainable mining operations. Based on these
Mr. Justice VAN DEVANTER delivered the opinion of the Court.. This is a suit to determine conflicting claims to underground waters collected and brought to the surface by a mining tunnel in Utah. The plaintiff (petitioner here) is a mining company incorporated in Delaware and the defendant an irrigation company incorporated in Utah. Each seeks to have the right to use the waters quieted in itself as against the other. The District Court, with some hesitation, gave a decree for the mining company, which the Circuit Court of Appeals reversed, with a direction that one for the irrigation company be given. Midway Irr.

The upshot of a corrupt and mismanaged licensing process appears to be hesitation from major mining firms that consider navigating such choppy regulatory waters too risky, while the applications of companies that do invest are not properly assessed.. I do think some of the bigger, more credible investors are probably put off when they look at that investment, Boden says. Rio Tinto has come and had a look around, I think on a couple of occasions, and hasnt ended up making serious investments, and that could well be because they have concerns about the way the sectors governed.. Several ongoing Ugandan mining operations appear to have been compromised by corruption at the heart of the licensing system. In 2013, Tibet Hima Mining Company won a contract to reopen the former colonial Kilembe copper mines; a deal that, according to two DGSM officials who spoke to Global Witness, went through at the instruction of President Yoweri Museveni.. Since then, the $175m project has made poor progress ...
For over an hour I was questioned on many topics. Here are a few snippets:. Why should the noise impacts from the proposed iron sands mining operation on blue whales be considered when seismic survey activity produces noise 1,000 to 100,000 times louder?. My answer: Seismic survey noise is very loud, but its important to note that seismic and mining noises are two different types of sound sources. Seismic surveys noise is an impulsive noise (a loud bang every ~8 seconds), while the mining operation will produce non-impulsive (continuous) sound. Also, the mining operation will likely be continuous for 32 years. Therefore, these two sound sources are hard to compare. Its like comparing the impacts of listening to pile driving for a month, and listening to a vacuum cleaner for 32 years. Whats important here is to considering the cumulative effects of both these noise sources occurring at the same time: pile driving on top of vacuum cleaner.. How many blue whales have been sighted within 50 km of ...

The increase of mining activities in the northern regions of Chile has brought about a new environment in terms of mobility to those areas where this industry has moved forward. This change has not only affected road traffic accidents on public roads of the surrounding mines, but also the inner organization of the mining companies, which must fulfill strict regulations, achieving the highest levels of safety. Given this situation, the current road traffic accidentology with respect to the northern regions of Chile has been analyzed in this paper. The results of the analysis have shown the relevant weight of the human factor and the state of the infrastructure related to the number of road fatalities. Thus, this paper provides solutions to combine the existing driver-centered technologies together with GPS systems that can track the movement of several vehicles and the design of safety berms in mine haul roads to mitigate the number of fatalities associated with mining activity ...
Location tracking has emerged as a potential new project for the Underground Mining Working Group. Systems for tracking, locating and monitoring the activity of people and things have many potential benefits because they improve situation awareness and lead to safer, more productive and more efficient operations.. On the surface, high-precision GPS has been a driver of new applications and capabilities in mining. However, GPS is unavailable for underground mines. Therefore, other emerging technologies for underground mining must be considered in order to uncover the benefits of precise and accurate location tracking.. With the advent of new underground location technologies, there is an identified need to develop an instructive document for mining companies looking to implement tracking within their mines based on mining-specific use cases. Ultimately, there is the need for greater interoperability between location tracking technologies to enable the enhanced precision and accuracy for ...

The goal of this article is to isolate the significant determinants that affect the decision of non-financial firms to hedge their risks. Our application is for the North American gold mining industry. The random variable considered is the selling price of an ounce of gold. We show that several factors related to maximizing the firms value significantly affect the decision to hedge the price of gold.
Where ASM is active in an area, it is either ignored by outsiders, or they intervene along three distinct lines as follows:. 1. Foreign mining company interventions. The miners may be treated as barefoot prospectors for large scale, usually internationally financed mining companies. If the deposits are small, they will not attract further interest from them. However, if the deposits warrant exploitation that is likely to give good returns on investment, these foreign companies will register mining claims over the area through national governments that are based in far-away capital cities. Generally the state sees the foreign mining companies as reliable partners who pay their taxes, are likely to abide by their corporate social responsibilities, and conform to environmental and other laws because they are also held to account by their shareholders or the media in the West.. Once the deal is secured, the majority world governments typically outlaw or confine ASM to certain areas, leaving the ...

OBJECTIVES: To investigate the following questions. (1) Is silica dust on its own, without the presence of silicosis, associated with an increased risk of pulmonary tuberculosis (PTB) in workers exposed to silica dust? (2) In the absence of silicosis is the excess risk dose related? (3) What is the predominant chronological sequence between the development of PTB and the development of silicosis after the end of exposure to dust? METHODS: A cohort of 2255 white South African gold miners has been followed up from 1968 to 1971, when they were 45-55 years of age, to 31 December 1995 for the incidence of PTB. During the follow up 1592 (71%) men died. Of these, 1296 (81%) had a necropsy done at the National Centre for Occupational Health (NCOH) to determine the presence of silicosis and PTB. The incidence of PTB in the cohort was studied relative to cumulative exposure to dust and the onset of silicosis. For the miners with necropsy, the incidence for PTB was studied relative to the severity of ...

Until Québecs 1987 Mining Act and Newfoundland and Labradors 1999 Mining Act were established, no set regulations existed for mining companies to take responsibility for the rehabilitation and revegetation of sites in these provinces. Abandoned mining sites exist across Canada, where all that is left is waste rock and fine fluid tailings. This can lead to environmental problems like water contamination, which can be especially dangerous to aquatic life if left untreated..

A strategic inquiry into underground coal mining in New South Wales, Australia, identified the need for non-market valuation studies and recommended increased use of benefit cost analysis in assessing individual mining proposals. This paper reports on the results of a choice experiment undertaken for a mine in the Southern Coalfield of New South Wales. Results from the study are used to aid the government decision by evaluating alternative proposals to continue underground coal mining operations. Results show that community wellbeing declines with increases in the kilometres of streams, the hectares of swamp, and the number of Aboriginal sites affected by mine subsidence. Community wellbeing increases with the length of time that the mine provides 320 jobs. Implicit price estimates from the choice experiment were incorporated into a benefit cost analysis of continued mining at the mine to assess the economic efficiency of a range of environmental restrictions on the proposed mining operations.

South Africas government delayed the implementation of a planned carbon tax to 2016, while saying it may impose new levies on mining companies to help fund the treatment of acid water seeping from disused gold mines.. The National Treasury two years ago said it planned to charge 120 rand ($11) on every metric ton of carbon emitted above a 60 percent threshold from 2014 and raise the rate by 10 percent a year for the following six years. Finance Minister Pravin Gordhan last year announced a delay in the tax, first proposed in December 2010, until 2015.. The National Treasury and the Department of Environmental Affairs have agreed that a package of measures is needed to address climate change and to reduce omissions, Gordhan said in his budget speech in Cape Town today. To allow for further consultation, the implementation of the carbon tax is postponed by a year to 2016.. The government will probably raise 8 billion rand to 30 billion rand a year from the proposed tax, according to Cecil ...
Respiratory Symptoms and Diminished Lung Functions Associated with Occupational Dust Exposure Among Iron Ore Mine Workers in Iran
SMCRA grew out of a concern about the environmental effects of strip mining. Coal had been mined in the United States since the 1740s, but surface mining did not become widespread until the 1930s. At the end of that decade, states began to enact the first laws regulating the coal mining industry: West Virginia in 1939, Indiana in 1941, Illinois in 1943, and Pennsylvania in 1945. Despite those laws, the great demand for coal during World War II led to coal being mined with little regard for environmental consequences. After the war, states continued to enact and expand regulatory programs, some of which required mining permits or the posting of bonds to ensure that the land could be reclaimed after mining was complete. But these state laws were largely unsuccessful at stemming the environmental impacts of surface mining. One problem was that the law varied from state to state, enabling mining operations to relocate to states where regulations were less strict. Meanwhile, surface mining became ...
There is increasing concern about the cardiovascular effects of mercury (Hg) exposure, and that organic methylmercury and inorganic Hg2+ may affect the cardiovascular system and blood pressure differentially. In small-scale gold mining communities where inorganic, elemental Hg exposures are high, little is known about the effects of Hg on blood pressure. In 2011, we assessed the relationship between Hg exposure and blood pressure (BP) in a cross-sectional study of adults from a small-scale gold mining community, Kejetia, and subsistence farming community, Gorogo, in Ghanas Upper East Region. Participants resting heart rate and BP were measured, and hair and urine samples were provided to serve as biomarkers of organic and inorganic Hg exposure, respectively. Participants included 70 miners and 26 non-miners from Kejetia and 75 non-miners from Gorogo. Total specific gravity-adjusted urinary and hair Hg was higher among Kejetia miners than Kejetia non-miners and Gorogo participants (median urinary Hg: 5
Mining-induced landslide is a man-made geohazard that has drawn increasing public attention. Studies have shown that these landslides are generally triggered by a confluence of factors including underground mining, topographical and geological conditions (Sun et al. 2007). The underground mining activities may alter the stability of a slope by (1) generating cracks on the slope, (2) causing instability to the slope body through extractions of the slope mass, (3) altering the stress field and geological features of the slope, and (4) altering the subsurface hydrological regime of the slope (Tang 2009).. Longwall mining is a common mining technique used in China. An increase in mining depth may result in a large cavity area known as goaf. The roof above the coal seam is allowed to collapse freely into the goaf upon extractions of the coal. This consequently results in an alteration to the stress state of the slope body, a sagging and bending of the overlying rock strata, a formation of tension ...

Because uranium mining is not consistently profitable, these mining operations are often abandoned for decades at a time - without any oversight or continued maintenance of the work area. Large drilling sites, tailing piles and mines are often left open to the forces of nature - leading to leaks into groundwater, dispersal of airborne uranium pollution and dust, and unsafe conditions for recreational visitors to public lands. And if and when these old mines are cleaned up, the cost burden usually falls on the American public.. Even more disconcerting is the toxic legacy left on public lands and sacred American Indian sites. Iconic landscapes have been marred, and sources of drinking water remain polluted. Manmade ponds containing uranium-contaminated water are left uncovered and used by native birds and other wildlife. These mines affect habitat for more than 100 sensitive species, including mule deer, mountain lions, imperiled California condors and highly endangered native fish. Groundwater ...

Emerging innovators are situated in areas with proven mining markets such as Canada, Australia and the USA, giving them rapid market access. To avoid direct competition with mining corporates, these startups are focusing on relatively stand-alone segments within the industry. For example, Earth AI sells the rights to its find for a stake in the project to a mining corporate rather than developing a mine itself. KoBold Metals is also expected to implement a similar model. Competition and Challenges Given the pressure on the mining industry to reduce its carbon footprint and the rise of ethical investing, investors are wary of funding the industry. This shifts corporates focus from innovation to retaining social license to operate and mitigating negative effects of their mining operations. For example, Glencore is using virtual reality to train miners, starting with its mine in Zambia in 2016, while BHP is incorporating the use of underground fleet management systems for task management, ...

BUCHAREST, Romania (AP) - The Canadian mining company Gabriel Resources said Thursday it would sue Romania for $4.4 billion in alleged losses over a gold mine that Romanias government decided not to approve following protests.. The company said the lawsuit would be filed Friday with a World Bank tribunal, arguing that Romania had violated the investment treaty … by licensing and then blocking the implementation of projects without due process and without compensation.. Jonathan Henry, Gabriels CEO, said the company had operated in good faith and…. complied with all applicable Romanian and European Union legal and regulatory requirements, to obtain permits for the mine. It was granted an exploration license in 1999 for the Rosia Montanta Mining project in which Gabriel owns an 80.69 percent share, and a Romanian state-owned mining company 19.31 percent.. The open mine project would have been Europes largest gold mine. Gabriel said it would have injected up to $24 billion into the ...

Environmental groups are pointing an accusing finger at irresponsible mining operators for the worsening state of the Palawan river.. According to the Friends of the Earth Japan (FoE-Japan) and the Kalikasan Peoples Network for the Environment (Kalikasan PNE), nickel mining operations in Palawan Island is to blame for the contamination of the Palawan river system. They said the river is already poisoned with unsafe levels of carcinogenic or cancer-causing chemicals.. During a recent present conference in Quezon City, the groups presented findings from an environmental field research study conducted in a river located downstream near the Rio Tuba Nickel Mining Corporations (RTNMC) mining operations and the Coral Bay Nickel Processing Plants operation.. The study, which started in 2009, analyzed water samples and revealed that present levels of hexavalent chromium (Cr-VI), a toxic and carcinogenic chemical, had already exceeded safe levels in the Togupon River. It showed that ...
Apr 09 2018 A number of compressive tests were conducted on iron ore pellets obtained from the Samarco pelletizing plant located at Ponta Ubu Brazil These pellets are formed by disk pelletizing of a mixture consisting of hematite iron ore (particle size less than 50 m) water and lime they are hardened in a traveling grate furnace and the nominal diameter varies between 9 and 16 mm.Feb 18 2021 Initially pellets with a bulk density of 2130 kg m angle of repose of 28 degrees and an average size of 12 mm were considered Due to the high computational cost of simulating a digital twin of the hold with particles in real size it was necessary to use scaled particle sizes without any need to scale the volume or mass of the cargo.The reduction of iron ore coal composite pellets wa s c rried out in the temperature range of 500 ~1200 C by thermogravimetry This study aims to investigate th e effect of particle size of iron ore on reduction behavior Three samples of different particle size were selected 2 ...
Moreover, in samples taken from the wells of several communities close to the mine, Indepaz found concentrations of heavy metals making the water unsuitable for human consumption. In the well in Provincial, researchers found arsenic and magnesium levels above those permitted for these metals. Specifically, in August 2016 they found arsenic levels of 0.026 mg/liter. The permitted value of arsenic in Colombia is 0.01 mg/liter. These metals, naturally present in rock and carbon, get dispersed in the environment by mining activity, contaminating the air, water and soil.. Cerrejón denies allegations that their operation is polluting local water resources, but Golda Fuentes, an investigator with Indepaz, contests this: El Cerrejón cannot possibly say that they are not contaminating the environment. We found that these concentrations are incompatible even with the Colombian standards for a healthy environment. The problem is that the laws applying to mining companies allow this ...

According to a 2009 study by the University of Witwatersrand and University College, London, there are approximately 288,000 cases of compensable silicosis in South Africa involving former gold miners who have contracted silicosis as a direct result of their work.. Additional research has shown that approximately 20 to 30 percent of former and current gold miners contracted silicosis because of their exposure to harmful quantities of dust underground. These and other similar studies show the same pattern-staggering numbers of miners, families and communities injured over decades and decades because of the mining industrys neglect.. The overwhelming majority of former gold miners are from areas historically known for supplying migratory labour to locations, including the Eastern Cape, Lesotho, Mozambique and Botswana. These areas are characterized by poverty and under-development. The Nelson Mandela Centre of Memorys website quotes Padraig OMalleys The Hope of Hope - South Africas Transition ...
California has a well-documented history of mining activity. The processes associated with mining for precious metals has yielded an increase in toxic inorganic arsenic levels in the mine wastes. Due to the relatively arid climate, the mobility and bioaccessibility of arsenic in these wastes are controlled by the size of the particle and arsenic concentration. This experiment intended to establish size and surface area trends in order understand the impact various mine wastes have on local communities. Three samples from the Randsburg Historic Mining District in Southern CA were used: Marigold East tailings, Marigold East waste rock, and Calico Mine tailings. Tailing samples were crushed and treated with various chemicals to extract precious metals while waste rock samples were mined but not processed. Samples were sieved into 11 distinct size fractions then analyzed for reactive surface area. Results indicated that the waste rock sample had a direct trend between its size and mass distribution with a

Porphyry System Characteristics. Porphyry-style gold systems host very large, bulk tonnage deposits that range from 2 to over 20 million ounces of gold and typically grade from 0.5 to 2 grams per tonne. Thus, major mining companies seek out porphyry style deposits for their economic scale and mine life - as evidenced by the private placement by IAMGOLD Corp late last year taking a 14% ownership of Colombia Crest based on the outcropping potassic alteration and discovery potential of the Companys immense land package in the prolific Middle Cauca Belt. Investments by other major mining companies have been announced in the Middle Cauca Belt, demonstrating a growing focus on Colombia as a source for new long-life gold mines.. Application for Warrant Extension. On May 10, 2010, the Company distributed 4,538,956 units at the price of $0.50 per unit by way of non-brokered private placement.
