ABSTRACT:
This process concerns the direct electroconversion of low grade manganese ores to high purity manganese dioxide product, which, among other applications, is ideally suited for use in dry cells. The process operating conditions are controlled such that impurities in the ore are substantially eliminated from the product. A decrease in impurity levels in excess of 100 fold can be achieved between the product and the ore feed.
