Reduction rate of MnO from two different manganese

2019-2-28 The present study investigates the reduction rate of MnO during the FeMn production process from two different manganese ores, namely Assmang and Comilog ores. The respective basicities of unfluxed Assmang and Comilog ores are 1.3 and 0.04, which do not fall in the range of industrial ferromanganese slags (0.2 1.2). Therefore, lime and quartz were added to the charge to
