Manganese dioxide is used to remove iron and manganese from drinking water by a process of catalytic oxidation.

Natural manganese ores specially selected for their high catalytic activity, free from contamination and with no additives, are used in the production of this manganese dioxide. The manganese content varies between 55 and 85% as MnO2, but the catalytic activity is not dependent upon the manganese content.
