There are two types of reduction smelting of ferromanganese: flux method (also known as low manganese slag method) and flux-free method (high manganese slag method). The principle of the flux method is the same as that of blast furnace smelting, except that electric energy is used instead of coke for heating. By adding lime, a high alkalinity slag (CaO/SiO2 is 1.3~1.6) is formed to reduce the loss of manganese.
Flux-free smelting without adding lime results in a low-iron, low-phosphorus and manganese-rich slag with low alkalinity (CaO/SiO2 less than 1.0) and high manganese content. This method has less slag, which can reduce power consumption, and the lower slag temperature can reduce the evaporation loss of manganese. At the same time, the by-product manganese-rich slag (containing 25~40% manganese) can be used as raw material for smelting manganese-silicon alloys, achieving higher results. Comprehensive recovery rate of manganese (more than 90%).
