  • Sulfide Ore Treatment Gold Silver Copper Cobalt

    A procedure was developed for recovering gold, silver, cobalt, copper, and zinc from a massive sulfide ore by a hydro metallurgical process. The procedure consists of (1) oxygen pressure leaching; (2) iron, arsenic, and copper removal from the leach solution by precipitation; (3) selective extraction of cobalt and zinc from solution; (4) electro

  • Gold extraction

    Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold

  • Gold(I) sulfide Revolvy

    Gold(I) sulfide is the inorganic compound with the formula AuS. It is one of two principal sulfides of gold , the other being gold(III) sulfide , AuS. Gold sulfides exist in nature as solid solutions with silver, which has the same covalent radius. Structure and preparation The compound crystallizes in the motif seen for cuprous oxide : gold is 2 coordinate,

  • Seafloor Massive Sulfides (SMS) Neptune Minerals

    Seafloor Massive Sulfides (SMS) SMS deposits are formed on the seafloor when hot water comes out of the seabed, hits the cold seawater and deposits its mineral load. This process results in “black smokers” which are the visual appearance of minerals precipitating in the cold water. They were first discovered in 1979 at 21 degrees north
