Copper sulfide ore, which accounts for 80% of the copper resource, is the major source for the metallic copper [1]. The major copper sulfide ores contain chalcopyrite (CuFeS 2), bornite (Cu 5 FeS 4), covellite (CuS), and chalcocite (Cu 2 S). The concentrates of copper from sulfides ores are generally performed by flotation and then processed by pyrometallurgic or hydrometallurgic routes to ...

The sulphide ore particles are wetted preferentially by oil and gangue particles by water. In this process, finely powdered ore is mixed with either pine oil or eucalyptus oil. It is then mixed with water. Air is blown through the mixture with a great force. Froth is produced in this process which carries the weted ore upwards with it. Impurities (gangue particles) are left in water and sink ...

· Important advances in research of sulphide ore textures in resent years have deepened our understanding of ore genesis of related mineral deposits. Pressure solution of sulphide minerals has been suggested as a mechanism for remobilization of ore materials, whereas pressure solution of the gangues is believed to raise the grade of the primary ores. We have known that precipitation of base ...

Hint:Silver is extracted from its sulphide ore by reacting with sodium cyanide which results in the formation of a complex and in the generation of photographic plate the unreacted silver bromide is washed using sodium thiosulphate solution which results in formation of another complex. Complete step by step answer:The silver can be extracted from its sulphide ore by cyanide process.

At hightemperature pressure leaching conditions, the formation of sulphuric acid from sulphides in the ore is favoured, however at medium and lowtemperature conditions (150–165oC and >140oC, respectively) elemental sulphur formation occurs. At these temperatures, the elemental sulphur is molten and causes issues in further leaching. A high yield of elemental sulphur reduces the oxygen ...
