Practically all ferro manganese plants use only raw lump oxide ores. Little sinter is used and possibly few operators have had experience with smelting sintered The focus is on smelting of ferromanganese, silicomanganese, and manganese metal in electric furnaces with different process types.

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 Standard SiMn with 18 to 20 wt pct Si and 70 wt pct Mn is typically produced from raw materials such as MnO-rich slag from the HC FeMn production Element Distribution in the Silicomanganese Production Process

12.4.2.2 Exothermic (Metallothermic) Process The exothermic process is generally used to produce high-grade alloys with low-carbon content. The intermediate molten alloy used in the process may come directly from a submerged electric arc furnace or from another type of heating device. Silicon or aluminum combines withon physical properties of steel. By adding manganese and ferro-manganese in the process of steel metallurgy, it has the role of a de-oxidizer and de-sulphurizer [18]. The reduction of ferromanganese slags to manganese metal in a rotary furnace has been reported [19]. Byung Su Kim et al. [20] recovered about 20% of the Re-Use of Silico-Manganese Slag MDPI

By adding manganese and ferro-manganese in the process of steel metallurgy, it has the role of a de-oxidizer and de-sulphurizer . The XRF analysis highlighted that the type of obtained slag from the ferro-alloy plant Tulcea is based on silicon-manganese. At a size fraction of slag <80 µm, a variation can be observed in the ferro alloys in India, the competitiveness of ferro alloys manufacture in India is increasingly being put into tight corners. However, ferro manganese is the type of ferro alloy which is also produced through Balst Furnace route. The scope of production of ferro manganese through BF route in Indian context is discussed in this paper. 83Production of ferro Manganese CORE

The plant of M\s. Singh Ferro Alloys is proposed to manufacture and process Manganese oxide, Manganese Dioxide and various Ferro Alloys. The factory is located 27 kms away from Nagpur city, at Plot No. C/156, MIDC Butibori, District Nagpur, (M.S.). The latitude and longitude of the proposed project are 20°56'46.67"N and Ferromanganese alloy is produced by the carbothermal reduction of MnO2 and Mn2O3 ores at high temperature using a submerged arc furnace (SAF). The production rate and chemical composition of liquid ferromanganese alloy in the SAF process are highly dependent on slag flux composition, coke amount, and temperature controlled by electric Ferromanganese Production in a Submerged Arc Furnace

Ferromanganese nodules were found in several cores from the Ioffe Drift (AI-2436, AI-3316, AI-3318) and in grab samples (AI-3653, AI-3654) from the fault channel north of the drift. Buried Fe–Mn nodules in various depth intervals from core AI-2436 were analyzed to investigate their formation, morphology, geochemical and mineralogical Manganese Ferroalloys Technology.
