GEO143 Mineral Webpages - Rhodochrosite

Rhodochrosite, a carbonate ore, is one of the most important Manganese ores (8). Mining for Manganese ore is generally done in open pits. Pure Manganese is produced by hydrometallurgical and electrolytic processes (8). Manganese is rarely used by itself due to its natural hardness. It is used in various metallic alloys, one such alloy is steel (3).
