Silver is found in lead, zinc, gold and copper ore deposits. The most important ore mineral of silver is argentite (Ag2S, silver sulfide). Silver is commonly extracted from ore by smelting or chemical leaching. Uses. Silver has been used for thousands of years for jewelry and decorative .

 · The chemical formula of that sulphide, calculated from chemical analysis of some flotation concentrates, is given in Table IV. Microscopic observation of polished sections of flotation concentrates re vealed that the main form of copper occurring was chalcocite, occurring as free grains or covering coal grains. Practically all of the copper occurs as that min eral. Moreover, occasional ...

From a processing point of view, copper ores could be divided into: Copper sulfide ores, where the pyrite content can vary from 10% to 90%. The predominant sulfide mineral in this ore is pyrite, but may also contain pyrrhotite and marcasite. Some copper sulfide ores also contain significant quantities of gold and silver.
