The Karnataka government has cleared a proposal of the Centre for reviving gold mining and auctioning of 13 tailing dumps spread over 1,003.4 acres at Kolar Gold Fields (KGF).
As much as 33 million tonnes of tailing dumps (extraction waste) is estimated to be lying at the 13 tailing dumps at KGF.
It is estimated that one tonne of dump yields one gram of gold on processing.
Bharat Gold Mines Limited, a PSU established in 1972 under the Department of Mines with its office at KGF, was closed due to economical unviability in 2001.
