Process Production Of Femn

review of manganese processing for production of,feb 22, 2018 production of ultrahigh-manganese steels is expected to result in significant increase in demand for low-carbon (lc) ferromanganese (femn) and silicomanganese (simn). current manganese processing techniques are energy intensive and typically yield a high-carbon product. the present work therefore reviews available literature regarding carbothermic reduction of mn oxides and ores, with the.production processes euroalliages,production processes. ferro-alloys are usually produced by the reduction of a metallic ore (generally oxide) by carbon with the addition of electric energy in a submerged arc furnace (smelting process) or by metals (metallo-thermic reduction), usually aluminium or silicon. high carbon ferro-manganese is produced by the reduction of manganese.
