| Abstract: | The manganese ore sample contains Mn 14.26%, TFe 11.90%, P 0.52%, P / Mn (0.036) > 0.006%, Mn / Fe < 3. The results of material composition study show that the manganese ore belongs to high phosphorus mixed ferromanganese ore with complex ore composition and structure. The exploration tests of coarse-grained tailing, weak magnetic separation, magnetic roasting manganese iron separation and the tests of raw ore screening, grinding fineness and strong magnetic separation were carried out. Through the test flow of raw ore grinding and strong magnetic separation, a manganese concentrate with the yield of 59.66%, concentrate Mn grade of 21.51% and recovery of 90.01% was obtained. |
