摘　　要：针对方铅矿单矿物,在铁球和瓷球介质下,改变磨矿条件进行磨矿浮选试验,考察磨矿对方铅矿矿浆电位及浮选行为的影响。磨矿试验表明,不同的磨矿介质或不同的磨矿条件(如磨矿时间、磨矿浓度、p H、Ca O用量)都会使方铅矿矿浆电位产生较大的差异。浮选试验表明,矿浆电位会直接影响方铅矿的浮选回收率,矿浆电位过高或过低都不利于浮选。当矿浆电位值保持在元素硫存在的电位区间内时,浮选回收率会出现最大值。Taking galena single mineral as the research object,the effect of grinding on the slurry potential and flotation behavior of galena was investigated by changing grinding conditions with iron sphere and porcelain sphere media.Grinding experiments showed that different grinding media or different grinding conditions(such as grinding time,grinding concentration,pH,CaO dosage)could dramatically change the pulp potential of galena.Flotation experiments showed that the pulp potential directly affected the flotation recovery of galena,and excessively high or low pulp potential is not conducive to flotation.When the potential value of the slurry was kept within the potential range of elemental sulfur,the maximum flotation recovery was achieved.
