2013-9-1  1. Introduction. 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.
