Reduction Mechanisms in Manganese Ore Reduction
Due to little Al 2 O 3 in the ores, the slag chemistry was simplified to the CaO-SiO 2-MnO system for Wessels ore and CaO-SiO 2-MnO-3 pct MgO system for Mamatwan ore. Each reduction path line was drawn between the two extreme points: zero percent manganese recovery and the 0 pct MnO point at the CaO/SiO 2 ratio of the ore.
