Silicomanganese Production – Process Understanding

inclusions, as MnO dissolved in the slag, and by production of metal high in silicon and low in carbon. The SiMn production is typically integrated with the manufacture of HCFeMn so that the slag from the HCFeMn production is reprocessed in the production of SiMn. In this way a very high total yield of manganese is achieved. 2.
