PREPARATION OF MANGANOUS CHLORIDE SOLUTION

摘要

PREPARATION OF MANGANOUS CHLORIDE SOLUTION A method for the preparation of manganous chloride solutions using copper as a redox intermediate in the reaction between manganese and chlorine. Treatment of manganese-containing materials with a copper solution results in oxidation and dissolution of the manganese and the formation of elemental copper. The copper is in turn dissolved by reaction with cupric or ferric ions, which are then regenerated by chlorine oxidation. The product may be used to prepare high purity manganese metal by electrolysis of the aqueous solutions.
