way to maximize the recovery of manganese through combined smelting processes of ferromanganese and silicomanganese alloys. If circumstances do not permit the recycle of ferromanganese slag through smelting silicomanganese alloy, the content of MnO in ferro-manganese slag should be low enough to discard or throw away. Empirically, the content ...

Ferro-manganese (Fe-Mn) is an important additive used as a deoxidizer in the production of steel. It is a master alloy of iron (Fe) and manganese (Mn) with a minimum Mn content of 65 %, and maximum Mn content of 95 %. It is produced by heating a mixture of the oxides of Mn (MnO2) and iron (Fe2O3) with carbon (C) normally as coke or coal.

The invention relates to the field of metallurgy of steels and alloys and can be used in the production of high-manganese steel. Known methods of production of high-manganese steel 110G13L in the electric arc furnace under a basic slag oxidation process; basic slag with the use of oxygen under a basic slag method of fusing and others [1].

One of the Ferro-silico-manganese uses is for molten steel de-oxidation process. The production of ferro-silico-manganese alloy uses manganese ore, quartz and iron ore as raw materials . The copper smelting slag is rich in iron and silicon, and thus is an attractive substitute for the quartz and iron ore in the ferro-silico-manganese production.

smelting process. In manganese processing: High-carbon ferromanganese. The primary product of the smelting process outlined above is a carbon-saturated ferroalloy containing 76 to 80 percent manganese, 12 to 15 percent iron, up to 7.5 percent carbon, and up to 1.2 percent silicon. It can be produced by two methods.

"Manganese ore is converted to fer-romanganese using the electric smelting process, and then used in the production of mild steel -ferromanganese production being a beneficiation process of adding value to the manganese ore itself," he explains. While the cost of electric power and the transport cost of ore to the smelter plant make

Silico manganese is an alloy with 60% to 68% manganese, 14% to 21% silicon, and 5% to 2.5% carbon. It is produced by smelting of slag from high-carbon Ferro Manganese or of Manganese ore with coke and a quartz flux in a submerged electric arc furnace. The process requires power consumption of about 3,800 to 4,800 kilowatt-hours per tonne.
