Beneficiation Studies on Copper Ore Samples from Rajasthan

Abstract

Copper is one of the important industrial metals in which India is deficient, with an annual production on only about 10000 tonnes against her estimated requirement of 1,24,000 tonnes at the end of the fourth plan period. Due to increasing demand of the vital metal, intensive efforts are being made to raise the output to about 50000 by the end of the fourth plan from the available workable deposits in the country. At Present workable deposits of copper ore occur mainly in Bihar and Rajasthan. The deposits in Bihar are being Worked by M/s. Indian Copper Corporation Ltd:, who are, raising their annual production from 10,000 tonnes to 16000 tonnes. The copper ore deposits of Rajasthan are located mainly in Khetri, dariba and Kolihan. Government of India has finalised setting up of an integrated plant to produce 31000 tonnes of copper metal annually at khetri which will include 10,000 tonnes from the adjacent line of Kolihan.
