    Mathematical Analysis of the Effect of Iron and Silica on

    The high iron-high silica manganese ore showed good reducibility with low melting temperature which makes it suitable for the production of manganese-rich slag. The investigation carried out on the reduction of siliceous manganese ore by graphite indicated that the manganese oxide is firstly dissolved into the molten MnO-SiO 2 -Al 2 O 3 -CaO-MgO slag, and then it is reduced from the slag 12 , 13 .

    Manganese Ore an overview ScienceDirect Topics

    Silicomanganese is produced by the carbothermic reduction of manganese ores in a submerged arc furnace. It contains 6568Mn, 12.518.5Si, and 1.53C. As in chromium ferroalloys, a high silicon content lowers carbon in manganese alloys. The smelting of silicomanganese requires a source for silicon as well as for manganese.

    how to process silica ore

    To obtain a product of low carbon and silicon content, manganese ore, lime flux, and coal are fused in a furnace, forming a melt rich in MnO. This is then contacted with silicomanganese or lowcarbon silicomanganese. The silicon in these alloys reduces the MnO to manganese metal and is itself oxidized into the slag. Read More
