The industrial production of high manganese steel melts with approx. 10–30 wt% Mn makes high demands on the utilized Mn‐bearing alloying agents in terms of chemical composition and cost‐efficiency. Conventional Mn‐bearing alloying agents are reviewed in this regard. A modified process route has been conceived for pyrometallurgical winning of special silicomanganese grades tailored for high manganese steelmaking. For each individual process step, namely manganese slag production, silicomanganese production, and optional desiliconization of silicomanganese, results of lab‐scale experiments are discussed.
