Manganese alloys include various ferromanganese and silicomanganese grades. High-carbon ferromanganese (HCFeMn) with a manganese content of 70-80 wt% and a carbon content of 6-7 wt% is the most widely used ferroalloy in terms of quantity. Ferromanganese alloys are produced by carbothermic reduction of ores containing iron and manganese oxide in a smelting-reduction furnace. During the production process, slags with a high content of manganese oxide is formed, which can be refined in further process steps to ferro-silicon manganese, low-carbon ferro-manganese (LCFeMn) or to manganese metal. In 2020, we observed FeMn prices at 900 - 2,000 €/mt, SiMn prices at 915 - 1,050 €/mt and manganese metal prices at 1,500 - 2,400 €/mt.
Manganese is added to alloy steel, such as structural steel, tool steel, stainless and heat-resistant steel.

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.
Ferromanganese alloy with a manganese content 75-90 wt% and a carbon content of 0.5-2 wt%.
Ferromanganese alloy with a manganese content 80-95 wt% and a carbon content of 0-0.5 wt%.
The compaction of Ferromanganese alloys of fine grain sizes into Ferromanganese briquettes briquettes can reduce dust losses and improve handling.
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 can be used as a substitute for flakes reducing dust loss and improving handling.
Besides flakes and briquettes, Mn metal can also be available in lumpy form.
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.
