摘　　要：对难选铜钼矿石回收率提高进行研究。过渡带矿石可选度较难,钼的原矿品位为0.058%时,钼的回收率为55.26%;铜的原矿品位为0.28%时,铜的回收率为53.26%,表明本试验研究的过渡带矿石属于极难选矿石。过渡带矿物难选的原因是辉钼矿表面氧化。改变矿物表面性质的方法为电场清洗矿物表面、碱洗矿物表面、酸洗矿物表面,三种方法比较,碱洗矿物效果最佳。The improvement of recovery rate of refractory copper molybdenum ore was studied.It is difficult to separate transition zone ores.When the grade of raw ore is 0.058%,the recovery rate of molybdenum is 55.26%;when the grade of raw ore is 0.28%,the recovery rate of copper is 53.26%,which shows that the transition zone ores studied in this experiment are very difficult to separate.The reason why the minerals in transition zone are difficult to be selected is the surface oxidation of molybdenite.The methods to change the surface properties of minerals are electric field cleaning,alkali cleaning and acid washing.Compared with the three methods,the effect of alkali cleaning is the best.
