【摘要】：为了有效提高多宝山斑岩铜钼矿的辉钼矿回收率,开发了铜钼等可浮浮选的工艺流程。系统地考察了浮选方案、捕收剂种类、磨矿细度、粗选p H值及药剂用量对辉钼矿浮选回收的影响。结果表明,与煤油、柴油相比,变压器油在水中具有较强的分散能力,且对辉钼矿的浮选选择性较优,因而在低用量条件下便可获得较高的钼回收率。另外,与混合浮选方案相比,等可浮浮选方案利用变压器油作捕收剂不仅可获得较优的铜钼混合精矿(钼回收率和品位分别为90.77%和0.80%),而且能提高钼精矿的钼回收率在18%以上、钼品位在5%以上。工业浮选试验结果进一步表明,采用等可浮浮选方案选别该斑岩铜钼矿是行之有效的。
[Abstract]:In order to effectively improve the molybdenum recovery rate of the porphyry copper-molybdenum ore in Dobaoshan, a floatable flotation process such as copper and molybdenum was developed. The effects of flotation scheme, collector type, grinding fineness, pH value of rough dressing and dosage of reagent on flotation recovery of molybdenum were systematically investigated. The results show that, compared with kerosene and diesel oil, transformer oil has stronger dispersion ability in water and better flotation selectivity for molybdenum. Therefore, a higher Mo recovery rate can be obtained under the condition of low dosage of kerosene and diesel oil. In addition, compared with the mixed flotation scheme, using transformer oil as collector, the isofloatable flotation scheme can not only obtain better copper-molybdenum mixed concentrate (the recovery and grade of molybdenum are 90.77% and 0.80%, respectively), but also increase the molybdenum recovery of molybdenum concentrate by more than 18%. Molybdenum grade is above 5%. The industrial flotation test results further show that it is effective to separate the porphyry copper-molybdenum ore by using the isofloatable flotation scheme.
