Chemical Sciences


Pilot Scale

Developing Agency:

Council of Scientific & Industrial Research (CSIR) - Institute of Minerals and Materials Technology (IMMT)

Investment required (in INR):

Rs. 2 crore

Brief Description

Description :

The developed technology has tremendous impact on bioremediation of coal and coke for removal of sulphur, manganese ore for removal of phosphorus, bauxite for removal of silica, iron ore for removal of alumina, and recovery of nickel from lateritic nickel ore, etc. The technology would utilize the huge quantities of lowgrade copper ores lying at the mine site to produce pure copper metal in the country. This would save our copper import and foreign exchange in addition to prevention of environmental pollution due to acid mine drainage.
