Jun 19, 2018· 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.

Ferromanganese is a ferroalloy with high manganese content (high-carbon ferromanganese can contain as much as 80% Mn by weight). It is made by heating a mixture of the oxides MnO 2 and Fe 2 O 3, 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 …

After increasing the surface area for leaching, the ore is then added to a leach tank of sulphuric acid and ferrous iron in the ratio of 1:6:1. This process recovers almost 92% of the manganese. In water leach, the mixture when subjected to water, the manganese is dissolved and the iron is undissolved and remains in the oxide form in solid state.
