Standard silicomanganese with 18-20 % Si and about 70% Mn is produced from a blend of HCFeMn slag with about 35 to 45% MnO, manganese ores, quartzite, (Fe)Si-remelts or off grade qualities, and coke. Sometimes minor amounts of MgO-containing minerals are added, e.g. dolomite [CaCO3⋅MgCO3] or olivine [(MgO)2⋅SiO2].
