It has the advantages of high efficiency, energy saving, environmental protection, dry beneficiation and waterless operation.
erected to beneficiate the residual clay ores. Development of the residual clay ore presents a number of problems. Minerali-zation is spotty or pockety, and metalization occurs as soft manganese oxide and concretionary nodules. The manganese is associated with oxide of iron in varying amounts.
The diagenetic to very low-grade metamorphic manganese ores of the Postmasburg manganese field provide a unique example of oxide-facies manganese ores in a Palaeoproterozoic palaeokarst setting. The ores are composed mainly of braunite group minerals, including braunite, partridgeite and bixbyite, with rare braunite II and Ca-poor, silica-depleted braunite.
