摘要

A new approach is proposed to recover iron and copper separately by controlling the pH using a two-step neutralization process. Iron sludge and copper sludge can be recovered separately. It is expected that copper sludge will dissolve in sulfuric acid to feed to solvent extraction process or feed directly to an existing copper smelter. Effluents from wastes and river water samplings were carried out several times from 2015 and three point's AMDs were selected to treat and recover the metals in Bor mine area in Serbia. The experiment results suggested the proposed process is promising.
