During the tapping and casting of manganese ferroalloys, fumes are generated and released to the working environment. The fumes are mostly composed of metallic oxides generated by reactions between high temperature molten metal and ambient oxygen in the air. From an HSE perspective, it is important to limit these emissions. However, to do so, it is important to understand fuming mechanisms and kinetics as well as their influence on fume composition, i.e element behavior during the oxidation process of liquid manganese ferroalloy. Silicomanganese are composed of a minimum of 65wt% Mn and 17wt% Si, 2wt% C as well as minor and trace elements. These elements include Fe, Ca, S and other elements originating from ore and reductants. Trace elements behavior from liquid silicomanganese alloy under an impinging air jet in temperature range of 1400-1700°C has been investigated in this work. Thermodynamic and kinetic conditions governing the generation mechanisms are discussed.
