Extraction of Copper from Copper Pyrite

Copper occurs both in native state as well as in combined state The chief ore of copper are Copper Pyrite (CuFeS2) Cuprite (Cu2O) Cupper Glance (Cu2S) Malachite [CuCO3 Cu(OH) 2] Extraction of copper Copper is extracted from is chief ore copper pyrite The various steps involved in the extractions are a Crushing and concentration The []

Smelting of low-grade copper scrap begins with melting in either a blast or a rotary furnace resulting in slag and impure copper If a blast furnace is used this copper is charged to a converter where the purity is increased to about 80 to 90 percent and then to a reverberatory furnace where copper of about 99 percent purity is achieved
