METHODS FOR CONVERTING MANGANESE DIOXIDE INTO A WATER-SOLUBLE MANGANESE SALTS

摘要

A water-insoluble manganese dioxide may be contacted with a solution having an effective amount of citric acid to form at least a portion of water-soluble manganese salt. The solution may have an initial pH of less than about 4. In a non-limiting embodiment, the solution may be fed into at least one equipment where the equipment has water-insoluble manganese dioxide therein.
