Bacteria could be a promising solution to this project. Similar approaches to use microbes are already being used for the mining of rare earth elements. Processing of copper requires bacteria that are already adapted to saline conditions. Therefore the scientists are focusing on bacteria from the sea

Microbial mining of copper sulphide ores has been practiced on an industrial scale since the late 1950s. Since then advances in microbial mining and the role of microorganisms involved in solubiliation of metals have assumed commerical importance. The fact that bioleaching processes save energy have a minimum pollution potential and are able to yield valueadded by
