The production of ferromanganese involves the smelting of a mixture of manganese ore, iron ore, and carbon sources to create an alloy with specific desired properties. The process typically takes place in a submerged electric arc furnace or a blast furnace. Here are the main steps involved in the production of ferromanganese:
Manganese oxide minerals have been used for thousands of years—by the ancients for pigments and to clarify glass, and today as ores of Mn metal, catalysts, and …

Manganese is considered a relatively rare metal as concentrations of it in ore of commercial importance are geographically limited. In nature, manganese is found in the form of oxides, carbonates, and silicates. Manganese ores are complex in the sense that they not only consist of a complex oxide mineral assemblage but these minerals are …
