Copper Ore
Name and Composition - Chalcopyrite (Copper pyrite): CuFeS2, Chalcocite (Copper glance): Cu2S, Bornite (Variegated copper ore): Cu5FeS4.
Physical Properties - In India copper is extracted from chalcopyrite which is brass yellow coloured massive mineral having metallic lusture and greenish black streak. Hardness is 3 to 4, sp. gr. is 4.1 to 4.3.
Mode of Occurrence - Mineralisstion generally occurs in the form of en-echelon shoots hosted by dolomite quartz chlorite–biotite, schist, augen gneisses etc.
Uses - Copper ore is used to extract copper metal, which in turn is extensively used in electrical appliances, electrical cables, winding wire, alloys, auto-ancillary, coinage, defence, die casting, railways and utensils.
Mineral based Industries – Benificiation plant and copper smelter, kitchen ware, utensils, handicrafts industries.
Industrial Prospects – There is wide scope for establishing industries like cable, electronics, chemicals, auto-ancillary.
