sulfide mineral Definition, Examples, Identification

Weathering may act to concentrate dispersed sulfides. Sulfide minerals are the source of various precious metals, most notably gold, silver, and platinum. They also are the ore minerals of most metals used by industry, as for example antimony, bismuth, copper, lead, nickel, and zinc.

Sulfide Minerals ThoughtCo

01/07/2017· Copper sulfides are a closely related mineral group, and they often occur together. In this bornite specimen are also bits of golden metallic chalcopyrite (CuFeS 2) and areas of dark-gray chalcocite (Cu 2 S). The white matrix is calcite. I'm guessing that the green, mealy-looking mineral is sphalerite (ZnS), but don't quote me.

Oxidation of Copper Sulfides and Secondary Sulfide

Secondary copper sulfide enrichment is widely accepted today as resulting from oxidation of copper sulfide minerals, downward migration of soluble copper sulfates, and precipitation as copper sulfide by reaction with primary sulfide minerals. Chalcopyrite is replaced preferentially to pyrite. Examples of sulfide enrichment above the water table as well as at and below the water table are well

01/09/2020· Few examples exist of activator applications to copper-sulfide minerals and an analysis of the reaction between NaHS and copper minerals has seldom been performed. We focused on NaHS activation for oxidized copper-sulfide minerals, such as chalcocite, bornite, and chalcopyrite, and investigated surface properties and interactions between copper-sulfide minerals and NaHS.

Examples of sulfide copper minerals are covellite, enargite, tetrahedrite, tennantite, bornite, chalcopyrite, chalcocite, and the like. The copper minerals occur in nature as copper ores. These copper ores are mixtures containing the copper bearing minerals and copper free minerals. Although the ore itself can be subjected to the present treatment process, it is preferred that a copper mineral
