A similar study was reported by Acharya et al. (2004) on fungal leaching of low grade Mn ore by Penicillium citirinum that was grown on mineral salt medium (MSM) (containing gm/l: 3 g NH4NO3, 1 g KH2PO4, 0.5 g MgSO4·7H2O and 100 g sucrose) for the leaching studies. The maximum solubilisation of Mn of 65% was obtained under optimised conditions ...

The general plan of work consists in steam-shovel mining the copper deposit followed by leaching the ore. From the crushing plant the ore will be moved by a belt and unloaded by a bridge that straddles the leaching tanks. The leaching tanks—six large concrete vats set end to end—are each 160 ft. long, 110 ft. wide, and 16 ft. deep.
