以煤油作为辉钼矿的主要捕收剂,以气溶胶形式进行加药,进行了煤油用量实验、浮选时间实验、pH值和磨矿细度影响实验,研究采用气溶胶浮选技术提高某铜钼矿钼回收率.气溶胶浮选技术可使铜钼混合浮选阶段钼回收率提高3%,且浮选时间缩短20%左右;在相同的回收率下,气溶胶浮选法使用的煤油用量可节省40%;气溶胶浮选的最佳磨矿细度为0.074mm占65%,浮选矿浆最佳pH值为9.与传统浮选工艺相比,气溶胶浮选技术具有浮选效率高、药剂用量少等特点,在低品位难选矿石浮选方面具有一定优势.
Using kerosene as the main collector of molybdenite, dosing with aerosol, kerosene dosage experiments, flotation time experiments, pH value and grinding fineness were conducted to study the effects of aerosol flotation technology Copper and molybdenum recovery of molybdenum. Aerosol flotation technology allows the recovery of molybdenum in the molybdenum and molybdenum mixed flotation stage increased 3%, and the flotation time was reduced by about 20%; at the same recovery rate, the aerosol flotation method used The amount of kerosene can save 40%; aerosol flotation fine grinding fineness of 0.074mm accounted for 65%, the optimal pH value of flotation slurry was 9. Compared with the traditional flotation process, the aerosol flotation technology has a floating Select efficiency, less dosage and other characteristics, low grade refractory ore flotation has some advantages.
