Abstract

Presently, the preparation of high pure manganese sulfate solution shows a long and complex process with low efficiency from the low grade manganese ore. The complete removal of calcium and magnesium ions coordinating with high recovery rate of manganese becomes one of the challenges for the conventional preparation of manganese sulfate. In the paper, the general removal methods of Ca2+ and Mg2+ including crystallization, electrolysis, extraction and chemical precipitation were reviewed at first. Moreover, a novel approach was proposed herein with the aid of theoretical calculation, in which Ba(OH)2 was used to adjust the pH value of manganese sulfate solution and BaF2 was used to completely remove Ca2+ and Mg2+. The initial experimental results show that the calcium and magnesium removal rate reached 95.11% and 97.93%, respectively, and the recovery rate of manganese keeps 96%, which shows the prospect of industrial application.
