Sep 01, 2014· Experiments with a mixed ore of iron (60wt%) and manganese oxides (10wt%) have demonstrated its highly reducible nature. With a fuel to ore ratio of 2:1, this manganese–iron mix was reduced very quickly to produce a bloom containing cast iron (Crew and Charlton, 2007). The authors suggested that a much lower fuel to ore ratio, perhaps as low
