In the past, all grades of refined ferromanganese were made by various modifications of multistep silicon reduction processes. Depending on the carbon content desired in the product, a manganese ore and lime mixture was allowed to react with the silicon in silicomanganese or low carbon silicomanganese in an open, electric-arc furnace. The equilibrium reaction is...

The only new silicon capacity since the early 1990s is by the Gulf Ferroalloys Company in Saudi Arabia. This plant is expected to have four furnaces and produce silicon metal, ferrosilicon, silicomanganese, and manganese alloys by late 1996.

Another common alloy of manganese is silicomanganese. It contains manganese, silicon, and carbon in addirion to iron. It is used for structural components and in springs. 

Manganese is mainly utilized as an alloy constituent in the steel industry as ferromanganese and silicomanganese. Pure metallic manganese is required in smaller quantities as an alloy constituent for copper, aluminum and special steels.
