摘要

Leaching kinetics are studied for manganese oxide of different degrees of oxidation in sulphuric acid solution, containing additions of oxalate ions, with different concentrations, basicity and temperature. Conditions are determined making it possible to avoid the occurrence of manganese oxide disproportionation reactions in acid solutions. Optimum conditions are found for dissolving manganese oxides in acid media in the presence of oxalate ions.
