Even though nearly all of the high grade natural iron ore in Minnesota has already been mined, advances in technology have found a use for lower grade iron ore, called taconite. The taconite is crushed, processed into hard, marble-sized pellets, and shipped to steel mills. The taconite pellets are melted in blast furnaces and then blown with ...

Sep 01, 2013· Although manganese is added into steel for its deoxidizing and desulfurizing properties (e.g. Gutzmer and Beukes, 2002), the occurrence of Mn in the iron ore raw materials causes harm to the reduction process of iron oxides in the blast furnace. Mn forms strong oxides, which are partially reduced in the blast furnace with parts entering the slag.

OREAS 174. OREAS 174 has been prepared from manganese ores sourced from the Glosam Mine situated within Postmasburg Manganese Field located in the Northern Cape Province of South Africa. The ores are composed mainly of braunite group minerals including braunite (3Mn2O3.MnSiO3), partridgeite (Mn2O3) and bixbyite (Mn,Fe)2O3.

Manganese fines. With their high manganese content, our fines have been developed for the production of silicomanganese (SiMn). This ore is used to improve process performance (less waste, reduced energy consumption), particularly in the production of agglomerates. Its low iron content makes it highly complementary to iron rich ores.
