CO Reactivity and Porosity of Manganese Materials
manganese in Assmang ore is mainly given by Mn 2O3. After CO reactivity test at 800 °C all Mn2O3 was reduced to Mn 3O4 and in addition, Mn3O4 was partly reduced to MnO. The oxygen content at 800°C of Gabonese and CVRD pellets is higher than of Gabonese and CVRD ores. The Gabonese and CVRD sinters have shown the highest oxy-

Reduction of Manganese Ores in CO-CO2 Atmospheres
Comilog is a high oxygen ore, where the majority of the ore is constituted by various tetravalent manganese minerals. When heated in reducing atmosphere, MnO 2 -oxides were reduced to MnO in a single step at temperatures below 550 °C. The rate was dependent on the particle size and CO-concentration.
