Ferromanganese alloy is produced by the carbothermal reduction of MnO 2 and Mn 2 O 3 ores at high temperature using a submerged arc furnace (SAF). The production rate and chemical composition of liquid ferromanganese alloy in the SAF process are highly dependent on slag flux composition, coke amount, and temperature controlled by electric power.
Using such a simple process model, inputs (mixed ore, slag flux, and coke) and electric energy can be determined to operate the furnace. For example, Tangstad, and Olsen 7 presented a simple mass and heat balance model for ferromanganese production.
The present thermodynamic approach and a simple process simulation model can be utilized for the understanding of the SAF process for ferromanganese production and also for the optimization of the SAF operation conditions to achieve the maximum Mn yield.

Ferro Manganese, often abbreviated as FeMn, is an essential alloy used in the production of steel. It is composed of iron and manganese and is known for its exceptional properties, making it a key ingredient in the steelmaking process.
To realize these combined strengthening mechanisms, about 10–15% of Mn content in steel is typically needed. 1 Therefore, the demand for ferromanganese (FeMn) alloys in steel industry has grown over time. Liquid FeMn alloy is typically produced by reducing natural minerals MnO 2 and Mn 2 O 3 by coke at around 1350–1400°C.
In the present study, the thermodynamic analysis of high carbon ferromanganese alloy production in SAF has been carried out using the FactSage thermodynamic databases. The slag fluxing strategy to improve Mn yield in the SAF process was studied.
