Abstract

Influencing the parameters of the crystallization process and the preparation of raw materials upon the quality of manganese acetate tetrahydrate was investigated. Optimum parameters were determined for the process of crystallization. Results are presented concerning studies on the influence of leaching the manganese carbonate upon the process purifying from calcium and chlorine impurities. A low-waste technological scheme is proposed for the production of high purity manganese acetate tetrahydrate.
