Combination Methods of Hematite-Braunite Ore Processing

详细

The material composition and process properties of hematite–braunite iron–manganese ore from Yuzhny Khingan deposit of Russian Far East are studied. The source of manganese in the ore is mostly braunite. The mineralogy and petrography of the ore and products of its processing are characterized. Noble metal minerals are found in the ore; the gold contains platinum and silver admixtures. Producibility of manganese concentrates of 37.85–46.46% Mn grade using the circuit of multi-stage magnetic separation in weak and strong magnetic fields and gravity concentration is experimentally proved.
