Extraction of Copper from Copper pyrite Grade 12

Blister copper consists of about 2% of impurities consisting of cliver, Glod, Zinc, Nicket etc. It is mostly purified by electrolytic method. A block of impure copper is anode, a strip of pure copper is cathode while solution of CuSO 4 containing dil H 2 SO 4 is e;ectrolyte. On passing current, impure copper dissolves and equivalent amount of

Copper is extracted from copper pyrites. After

Copper pyrites contains only 2-3% of copper. The rest of ore contains iron as sulphide, silica, silicious materials, sulphur, arsenic etc as impurities. Froth floatation is carried out by xanthate and pine oil. The froth is collected and dried when concentrated ore is obtained which contains 25-30% of Cu.
