Recovery of Metallic Values from Abandoned Copper Mines and Lean Ores by In-situ Bio-leaching
Huge quantity of copper is lost in Crown, Sill, Rib Pillars, hanging wall, foot wall and unexploited ore bodies in several closed underground copper mines and old worked out stopes of Hindustan Copper Limited at Mosaboni and other places. These mines might have been uneconomical to work with conventional mining methods. However, huge quantity of mineral reserves is lost due to their closure.Chemical and in-situ bio-wash leaching, if tried can provide an answer to facilitate the recovery of metallic values economically. Encouraging results were obtained during an experiment at North Badia Mines at Mosabani in the past. Though the experiments were not completed but whatever results obtained were very encouraging and can be successfully tried to make it viable. The results of the experiments are discussed here and a plan is suggested to recover copper from such mines.
