pdf hydrometallurgical processing of manganese ores,haghshenas et al. 6 reported that about 94 of the manganese ore is converted into manganese alloy, out of which the biggest use of manganese is for the production of steel and cast iron. no satisfactory substitute for manganese in steel production has been identified which combines its relatively low price with outstanding technical benefit..recovery of manganese from oxidized ores as ironand,duction of iron and steel the metallurgy of manganese was developed simultaneously with that of iron. there were enough high-grade ores available to this country so the process was essentially a reduction with carbon in a blast furnace to produce a manganese-iron alloy ( ferromanganese )..
