The manganese supply chain was divided into modules representing primary (on-site) and associated upstream and downstream processes for each step of the manganese alloy production process (Fig. 1). Manganese ore is mined via conventional surface and underground mining methods.
However, Ferro-alloys are usually produced by the reduction of a metallic ore (generally oxide) • by carbon with the addition of electric energy in a "Submerged Arc Furnace" (smelting process); • or by metals (metallo-thermic reduction), usually aluminum or silicon. The submerged arc process is a reduction smelting operation.
Thus, the development of new high-carbon ferrochrome smelting processes is crucial for reducing coke powder usage and power consumption in smelting, as well as improving chromium recovery rates and market competitiveness.
Initially, the production process was rudimentary, and the alloy was created by smelting manganese ore, iron ore, and silicon in a blast furnace. Over time, advancements in technology and metallurgical science refined the production methods, making FerroSilicon Manganese a standardized and widely used alloy.
