Abstrak

The useful mineral in a high-iron manganese ore in Zambia is hematite and various manganese minerals, and the iron grade is 44.71%, the manganese grade is 17.86%. In order to make an appropriate sorting process, the chemical composition, mineral composition and embedded characteristics of the ore were studied by optical microscope, chemical analysis and X-ray diffraction. The research results show that the main iron mineral is hematite, the content is 61.53%; the main manganese minerals are anthracite, limonite and soft manganese, the content are 18.62%, 4.82% and 4.66%. Finally, pre-concentration-magnetization roasting-magnetic separation test was carried out on the ore, and the average TFe grade was 67.97%, the average recovery rate was 94.67%; the average Mn grade was 49.85%; the average recovery rate was 88.24%. The research results have certain guiding significance for the formulation of the ore sorting process, and also can provide a reference for similar ore.
