  • The role of manganese ore reduction morphology

    2019-6-15  Manganese ores vary widely in their mineralogical and chemical composition. The main South African manganese ores fall into two groups, carbonate containing ore (Mamatwan-type) such as Mamatwan or Gloria ore (different mines from the same ore body) or high manganese and iron-containing ores (Wessels-type) such as Wessels or Nchwaning ore, (Kleyenstüber, 1984).
