The process from manganese ore to the final manganese product is closely related to the target demand and the grade (manganese content) of the original ore. Most of the rich manganese ores containing at least 30% manganese are smelted by a pyrometallurgical process to be used in the metallurgical industry. The mining of poor …

The original supply in the manganese flow is composed of manganese from ore and scrap. Ore included manganese and iron ore, from which iron is principally recovered, but its manganese content is also used (Nakajima et al., 2008).In the refining stage, ores and scrap are transformed into various intermediates by smelting, …

In the oxide type manganese ore, the manganese is often present in the insoluble form of Mn 4+ and iron often exists in the state of Fe 3+. In order to obtain soluble Mn 2+, Mn 4+ must be converted into Mn 2+, therefore, reductants are applied to reduce Mn 4+ into Mn 2+ during the acid leaching process (Named as direct reduction leaching).

The beginning of the Manganese ore processing involves a multistage crushing workflow. From there, the production of ferromanganese, the manganese ore is mixed with iron ore and carbon and then reduced either in a blast furnace or in an electric arc furnace. The resulting ferromanganese has a Manganese content of 30% to 80%.
