Abstract
Ferro-manganese or ferro-silico-manganese containing at least 55% Mn is produced by heating a finely divided preferably pelletized mixture of a manganese ore, with Mn to Fe ratio of more than 4, and a carbonaceous material such as anthracite, coking coal, coke breeze or graphite, with or without a flux such as limestone, to a temperature between 1120 DEG and 1250 DEG C., e.g. in a sintering machine, rotary kiln, refractory container or sagger, until at least 75% of the iron content and at least 40% but not all of the manganese content of the ore is reduced to metal to form an intermediate Mn-Fe alloy or Mn-SiO2-Fe complex (wherein the Si content may be 8-25%), the final alloy being produced from the intermediate alloy or complex and unreduced oxides by further reduction, e.g. using a blast furnace or submerged or open-arc electric furnace. Sufficient carbonaceous material may be added to the initial mixture for the complete reduction and any requisite carbon in the final alloy. If insufficient, the partly reduced mixture containing the intermediate alloy or complex is protected from oxidation while being transferred to the final reduction region, e.g. by the CO-containing gas generated in the final reduction.
