Sulfides, Selenides and Tellurides: rebellious and ...

Pyrite, galena, sphalerite, and chalcopyrite are all common sulfide minerals that are found in many precious metal veins and other hard rock deposits. When metals combine with sulfur, the resulting mineral is called a sulfide. These minerals are the most important sources of most base metals like copper, lead and zinc.

Sulfide minerals Howling Pixel

Prominent copper sulfide minerals include Cu2S (chalcocite) and CuS (covellite). In the mining industry, the minerals bornite or chalcopyrite, which consist of mixed copperiron sulfides, are often referred to as "copper sulfides". In chemistry, a "binary copper sulfide" is any binary chemical compound of the elements copper and sulfur.

Part Three Resources and Technology Princeton University

THE GEOLOGY OF COPPER Copper occurs in three different mineral groups (see table 51). In sulfide mineral deposits, the copper is linked with sulfur. In carbonate deposits, the copper occurs with carbon and oxygen. In silicate mineral deposits, the copper is linked with silicon and oxygen. The latter two groups are also termed oxide ores.

Abstract. Copper is most commonly present in the earths crust as copperironsulphide and copper sulphide minerals, for example, chalcopyrite (CuFeS 2 ), bornite (Cu 5 FeS 4) and chalcocite (Cu 2 S). Copper also occurs to a lesser extent in oxidised minerals, for instance, malachite (Cu 2 (OH)CO 3 ), azurite (Cu 3 (OH) 2 (CO 3) 2)...
