Sorption of Zn(II), Cu(II), Fe(III) on carbon adsorbents from manganese sulfate solutions Original Research Article

Sorption of Zn2+, Cu2+, Fe3+/Fe2+ on carbon adsorbents under static (batch) and dynamic (columns) conditions from model and industrial MnSO4 solutions has been studied. The industrial solutions were obtained by reducing acidic leaching of manganese and pyrite concentrates. The initial manganese concentration was ∼35 mmol/l and concentration of Zn2+, Cu2+, Fe3+ ions was ∼0.2 mmol/l. It was found out that a complete separation of Mn2+ and Me2+(Fe3+) ions is possible under dynamic conditions. As a result purified MnSO4 solutions are obtained which can be applied in MnO2 electroevolution processes.
