Jun 19, 2018· The process is similar to that used in the silicothermic production of medium C FeMn. Highpurity ores are used and in particular ores containing Fe and P are to be avoided. An artificial Mn ore produced as a high grade ore is particularly suitable because of its low impurity level and because all the Mn is present as MnO.
