of manganese alloys requires ores with manganese content greater than 30% and manganese/iron ratio greater than 5 [1]. Ores with a low manganese content (~12% or less) [3,4] can be utilized in the production of manganese pig iron [5, 6] . The global production of raw and up- graded manganese ore is assessed to be around 17 million tonnes [5,7].
