extraction of copper ore

Extraction. The extraction of copper also involves many steps. The ore used for extraction is copper pyrites. This ore is crushed, concentrated and then heated in the presence of air. During heating the moisture gets expelled and the copper pyrites gets converted to ferrous sulphide and cuprous sulphide.

Method Of Concentrated Of Copper Of Copper Ore

The copper is formed of by the reduction of Cu2O and Cu2S in the process of extraction of copper from its sulphide ore. This reaction gives 98% copper by auto reduction. Electrolytic refining can be used for obtaining 99.9% pure copper. The reaction followed in the process is given below: 2CuFeS2 + O2 ----> Cu2S + 2FeS + SO2. Finally

Metallurgy of copper

The role of silica in the metallurgy of copper is to remove the iron oxide obtained during the process of roasting as 'slag'. If the sulphide ore of copper contains iron, then silica (SiO 2) is added as flux before roasting. Then, FeO combines with silica to form iron silicate, FeSiO 3 (slag).
