  • role
  • This finding is an extension of the Miller-Urey experiment and it is suggested that carbonyl sulfide played a significant role in the origin of life . (wikipedia.org)
  • zinc
  • Zinc sulfide (ZnS) is one of the first semiconductors discovered and it has traditionally shown remarkable fundamental properties, including a direct wide-bandgap semiconductor, the presence of polar surfaces, excellent transport properties, good thermal stability, high electronic mobility, etc. (sciencewatch.com)
  • Base metal massive sulfide deposits within felsic volcanic piles are typically zoned from a copper-rich base to a zinc [plus-minus sign] lead-rich top. (edu.au)
  • copper
  • Scientists from the U.S. Geological Survey are evaluating the potential for undiscovered sulfide deposits containing varying amounts of nickel, copper, platinum-group metals, and cobalt in the Lake Superior region as part of an ongoing effort to assess the mineral potential of the United States. (usgs.gov)
  • Similarities between rocks of the Midcontinent rift and rocks that host the Voisey Bay nickel-copper-cobalt deposit in Labrador, Canada, and the Noril'sk nickel-copper-platinum-group-metals deposits in Russia suggest a high potential for such sulfide deposits in rocks associated with the 1.1-billion-year-old Midcontinent rift in the Lake Superior region. (usgs.gov)
  • Current emphasis is on evaluating the potential for sulfide deposits containing varying amounts of nickel (Ni), copper (Cu), platinum-group metals (PGM's), and cobalt (Co) because of the importance of these metals to the Nation and the recent availability of much new information on these kinds of mineral deposits. (usgs.gov)
  • As the sulfide droplets segregate, they scavenge metals such as nickel, copper, platinum (Pt), and palladium (Pd) from the magma. (usgs.gov)
  • The process of mining copper and nickel are so different from the process of mining iron ore that we, as residents of this area, and anyone who values the BWCA and their experiences here, must look carefully at the downside of sulfide mining and the likelihood of "acid mine drainage" into the BWCA.

  • Please visit as many of the resources listed as possilbe until you are comfortable with your understanding of the difference between iron mining and copper hard rock sulfide mining. (elyminnesota.com)
  • Artemis Resources Ltd ( ASX:ARV ) (FRA:ATY) (OTCMKTS:ARTTF) has reported a 152-kilotonne indicated sulphide resource for its 70%-owned Ruth Well Nickel-Copper Project in the West Pilbara area of Western Australia. (proactiveinvestors.com)
  • Chalcopyrite Mineral Stone, Copper Iron Sulfide, Isolated On. (123rf.com)
  • The movie aims to bring awareness to two proposed sulfide-ore copper mines that opponents say would threaten Lake Superior and the Boundary Waters Canoe Area. (perfectduluthday.com)
  • acid
  • Consideration of mineral-solution equilibria in the Fe-S-O system suggests that proximal Archean-type massive sulfides are deposited from high temperature, mildly acid, and reduced chloride-rich solutions (within environment I) which mix with sea water at the top of the volcanic pile. (edu.au)
  • Application
  • In this study, the characterization of a sulfide-oxidizing nitrate-reducing biomass obtained from an anoxic biotrickling filter was performed through the application of respirometric and titrimetric techniques. (upc.edu)
  • form
  • The largest concentrations of sulfides appear to form in channels or conduits through which new magma flows into the magma chamber. (usgs.gov)
  • below
  • In the Noranda and Matagami mining camps in the Archean Superior Province of eastern Canada chalcopyrite is concentrated with pyrrhotite-pyrite [plus-minus sign] magnetite in the base of the massive sulfide ore lenses or xvithin a stringer zone below the lenses. (edu.au)
