Abstract
The key mechanisms of selective recovery of manganese ions from mine water by combination of chemical and electrochemical methods are studied. The authors present the efficient parameters of oxidation deposition of ions Mn2+ in electrolysis solutions of active chlorine forms generated in chloride-containing solutions under electric treatment and subsequent removal of dispersed phase manganese from the solutions. The mechanism of generation of dispersed phase manganese by electric treatment of acid mine water at copper-sulfide deposits is offered
