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/lodes 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.
