Application of relevant Manganese types

High Carbon Ferromanganese (HCFeMn):

High carbon ferromanganese (HCFeMn) is the most widely used ferroalloy in terms of quantity. It usually has a manganese content of 70-80 wt% and a carbon content of 6-8 wt% During the production process, slags with a high content of manganese oxide are formed, which can be refined in further process steps to Silicomanganese (SiMn), Low carbon Ferromanganese (LCFeMn) or to Manganese metal.

Medium Carbon Ferromanganese (MCFeMn):

Ferromanganese alloy with a manganese content 75-90 wt% and a carbon content of 0.5-2 wt%.

Low Carbon Ferromanganese (LCFeMn):

Ferromanganese alloy with a manganese content 80-95 wt% and a carbon content of 0-0.5 wt%.

Ferromanganese briquettes (FeMn briqs): 

The compaction of Ferromanganese alloys of fine grain sizes into Ferromanganese briquettes briquettes can reduce dust losses and improve handling. 

Manganese metal flakes (Mn metal flakes):

Electrolytic manganese flakes, commonly referred as manganese metal flakes, with a minimum manganese content of 99.7 wt%, are mainly used by steel mills.  

Manganese metal briquettes (Mn metal briqs):

Manganese metal briquettes can be used as a substitute for flakes reducing dust loss and improving handling.

Manganese metal lumps (Mn metal lumps):

Besides flakes and briquettes, Mn metal can also be available in lumpy form.

Silicomanganese (SiMn):

Silicomanganese has additional silicon, which acts as a more powerful deoxidiser. Compared to the standard FeSi75 and HCFeMn, the use of silicomanganese also leads to a smaller increase in carbon, which makes it a preferred substitute.
