Ferromanganese and silicomanganese alloy are a widely used deoxidizing agent for steelmaking, which is produced by carbothermal reduction of oxide ores in electric arc furnaces. As an environmentally hazardous by-product, electric arc furnace (EAF) dust of ferromanganese and silicomanganese production units is formed from volatiles and fines and collected by dedusting of the off-gas from manganese alloy smelting furnaces. The amount of dust and sludge from dry and wet off-gas cleaning is estimated to be about 120 kg per ton of ferromanganese and silicomanganese alloy production.1) Storage of EAF dust presents a long-term environmental concern. A usual way to treat the EAF dust is returning it into electric arc furnace to reuse Mn and Si. However, a great amount of other elements, such as K, Na and Zn, are also reused in the recycle, which is harmful for normal operation of electric arc furnace.2) Many investigations on recycling of valuable components from EAF dust were carried out. Ghafarizadeh3) studied recovery of manganese from EAF dust by reductive leaching in sulfuric acid with oxalic acid as reducing reagents. Over 90% of manganese, in the form of MnSO4, was leached out.
