Silicomanganese Production – Process Understanding

The main source of Mn in raw materials for SiMn production is Mn-ore and Mn-rich slag from the high carbon FeMn production. The amount of slag per tonne of SiMn metal is mainly determined by the ore/slag ratio. Increasing share of FeMn slag at expense of Mn-ore will lead to larger slag/metal ratio in the SiMn process.

LOW CARBON SILICOMANGANESE LCSiMn - Eramet

There are two families of Mn alloys called ferro-manganese (FeMn) and silico-manganese (SiMn). Silico-manganese adds additional silico n which is a stronger deoxidizer and which also helps to improve some mechanical properties of steel. In each family carbon is controlled and is lowered when producing ''refined'' grades.

From the top apex of Figure 7 are drawn straight lines having constant CaO/Al2O3 ratios, called R-ratios. This R-ratio is much more important in SiMn production than the so-called lime basicity ratio [(CaO+MgO)/SiO2] used by many producers. Using the R-ratio, any MgO in the slag should be added to CaO in the numerator.
