There are no rigid ore-requirements for ferro-manganese produced in the blast furnaces. The high carbon ferromanganese is the most important grade of ferromanganese, which is produced by carbothermic reduction of high-grade Mn ores, and low iron content. Ferromanganese is used to add manganese in steel equivalent to 200 series stainless

16.08.2017All of the reduction reactions are highly endothermic and a high amount of thermal energy is required for the accomplishment of these reactions [ 1, 2 ]. The most abundant forms of the manganese oxides are MnO 2, Mn 2 O 3, Mn 3 O 4 and MnO. These compounds dissociate during heating. 2MnO 2 = Mn 2 O 3 +1/2O 2. 3Mn 2 O 3 = 2Mn 3

These deposits are only partially used in ferromanganese production. The ores contain large quantities of iron and thus the Mn / Fe ratio is low, 3 - 4. Iron appears partially in ore as individual hematite and goethite grains and the remainder of it is in the manganese grains. The laboratory tests showed that the Mn / Fe ratio increased up to 11 when the pre
