Extraction method of ferromanganese:
Reduction smelting of ferromanganese has two kinds of flux method (also known as low manganese slag method) and no flux method (high manganese slag method). The principle of the flux method is the same as that of blast furnace smelting, except that electric energy replaces the coke used for heating. By adding lime to form high basicity slag (CaO/SiO2 1.3~1.6) to reduce the loss of manganese. A low iron and low phosphorus manganese rich slag with low alkalinity (CaO/SiO2 less than 1.0) and high manganese content is formed by fluxless smelting without lime. In this method, the amount of slag is small, the power consumption can be reduced, and the evaporation loss of manganese can be reduced because of the low slag temperature. At the same time, the by-product manganese rich slag (containing 25~40% manganese) can be used as the raw material for smelting manganese silicon alloy, and the comprehensive recovery rate of manganese is higher (more than 90%).
