Extraction of cu

EXTRACTION OF COPPER FROM SULPHIDE ORE Large amount of copper are obtained from copper pyrite (CuFeS2) by smelting. Ores containing 4% or more copper are treated by smelting process. Very poor ores are treated by hydro-metallurgical process. EXTRACTION OF COPPER BY SMELTING PROCESS Following steps are involved in the extraction of copper
