The copper metal is mainly extracted from is sulphide ore copper pyrites (CuFeS2) .The Cup obtained can be reduced to copper by treating with →3O22Cu2O + 2SO2
· The traditional route for extracting copper from sulfide ores is smelting. Yet there is a growing case for leaching sulfides from lower grade ore bodies and especially for those ore bodies containing problematic elements like arsenic, which make smelting less economical. Smelting is increasingly expensive because, in general, smelters require a content of more than 25 per cent copper.
