  • Manganese Orean overview ScienceDirect Topics

    Manganese ore is required in iron making to control the manganese content of the hot metal in the desired range. Unlike other plants where manganese ore lump is used directly in blast furnace in VSP it was proposed to use manganese ore fines in sinter productions. This would ensure much more consistent manganese content in the hot metal.

    Both can be realized with or without fluxes depending on the raw materials. The first method is quite similar to the blast furnace practice and it aims to reduce manganese into the alloy in one stage usually with assistance of basic fluxes (CaO MgO) or using a basic ore decreasing silica activity in the slag and increasing the activity of MnO.
