US4002717A - Refining of manganese oxide ores - Google
This invention provides a method for treating manganese oxide ores in an aqueous medium, with hydrogen halide or sulfuric acid, and a hydrogen sulfide or a metal sulfide, e.g. an ore. A leach liquor containing the desirable metal halides is then separated from the solid, insoluble residue. Any iron value in either the manganese oxide ore or in any metal sulfide ore present is not dissolved or ...

Manganese - USGS
Manganese is an essential element for modern industrial societies. Its principal use is in steelmaking, where it serves as a purifying agent in iron-ore refining and as an alloy that converts iron into steel. Although the amount of manganese consumed to make a ton of steel is small, ranging from 6 to 9 kilograms, it is an irreplaceable component in the production of this fundamental material.

Manganese Removal - an overview ScienceDirect Topics
Manganese removal can also be achieved using wetland systems; however, it is clear that iron needs to be removed before manganese removal can effectively take place. A maximum removal of 94–97% (116–142 mg m −2 d) for total iron and of 69–77% (6.2–7.9 mg m −2 d) for Zn 2+ were observed for a planted soil surface flow wetland system ...
