Effect of slag basicity in ferromanganese production using medium .

The chemical composition of ferromanganese and slag was analysed with X ray fluorescence. From this experiment, the optimum slag basicity was 0.8 that produced 8.2 kg of ferromanganese with 78.1% Mn, 12.7% Fe, and 8.9% Si. It resulted from 30 kg of manganese ore, 7.5 kg of cokes, and 12 kg of limestone.

Ferromanganese Wikipedia

Ferromanganese, a ferroalloy with high content of manganese, is made by heating a mixture of the oxides MnO2 and Fe2O3, with carbon, usually as coal and coke, in either a blast furnace or an electric arc furnace type system, called a submerged arc furnace. The oxides undergo carbothermal reduction in the furnaces,.
