Selective Chemical and Biological Metal Recovery from Cu-Rich Bioleaching Solutions

Abstract:

Pregnant leach solutions (PLS) resulting from bioleaching of copper concentrate from Kupferschiefer are characterized by low pH and high concentrations of Fe, Cu, Zn as well as significant amounts of Ni and Co. In order to recover the valuable metals for further processing, chemical methods and a novel biological-induced technique that promotes selective metal recovery and sulfate removal from acidic liquors were applied and a process scheme was developed.
