Abstract the effect of coke and bituminous coal on the reduction of mediumgrade manganese ore in ferromanganese production was investigated charges of 30 kg medium grade manganese ore 12 kg limestone and varied amounts of coke and coal were smelted in a submerged electric arc furnace saf at temperatures of 1300 c to 1500 c
May 28 2019 the authors proposed the selective reduction of p from steelmaking slag to enable the recycling of steelmaking slag for the sintering process and for the extraction of p and mn separately by decreasing the basicity of the slag and increasing the temperature of the reduction fe and p were reduced to the metal while most of the mn remained in the slag
The small amount of manganese ore produced in the united states is generally used as a pigment in the manufacture of brick 5 as of 1992 there were four companies that produced manganes e manganese oxide ferromanganese or silicon
