ABSTRACT:
In a method of preparing high-purity manganese compounds, wherein the method comprises adding a member selected from ferromanganese and metallic manganeses to an aqueous electrolyte-containing solution, dissolving said member while stirring and maintaining a pH of 2 to 9, and then removing insolubles by filtration and recovering solubles by precipitation, heavy metal elements as well as non-metllic elements, such as P, Si, etc. can be removed efficiently, and high-purity manganese compounds of stable quality can be prepared.
