探讨自磨和常规磨矿方法对德卢斯辉长岩铜-镍硫化矿浮选性能的影响。在同样的磨矿粒度下,用自磨矿浆进行浮选,铜、镍和钻的回收率较高而尾矿中残存的硫较少。用球磨矿浆进行浮选,即使增加捕收剂加入量,尾矿中残存的硫也不会低于自磨所达到的水平。根据精矿和尾矿矿样的矿物学研究可以队为,在这两种磨机中,磨矿介质和硫化矿物之间的电化学作用对硫化矿浮选过程的影响,大于对矿样的破碎特性的影响。 Effect of self-grinding and conventional grinding methods on flotation performance of Duluth-gabbro copper-nickel sulphide ore mines. At the same grinding particle size, flotation with self-grinding slurry resulted in higher copper, nickel and diamond recovery with less residual sulfur in the tailings. Flotation with ball mill slurry, even with increasing the amount of collector, residual sulfur in the tailings will not be lower than the level achieved by self-polishing. Depending on the mineralogy of the concentrate and tailings samples, teams can be employed. In both mills, the effect of the electrochemical interaction between the grinding media and sulfide minerals on the flotation process of sulfide ores is greater than for the mineral samples Impact of broken character.
