Microbial recovery of metals from solids

Currently, these microbiological technologies are used on an industrial scale only for the recovery of copper, gold, or uranium from ores [9, 25, 30]. Subjecting refractory gold ore to microbial treatment prior to conventional chemical extraction can substantially increase recovery by promoting biological transformation of the minerals the gold is trapped in [32, 33 ].
