在流程首部采用能分出大量废弃尾矿的过程是现代发展选矿的主要任务。重介质选矿是比较完善和生产能力鞍大的方法,它不仅能有效地代替选矿最初阶段的重选过程,而且可作为某些矿石浮选的预先选别作业。世界上共有60多个有色和稀有金属选矿厂采用这种先进的方法。
The main task of modern development beneficiation is to adopt at the head of the process the ability to separate large amounts of abandoned tailings. Heavy medium beneficiation is a relatively complete and productive method of saddle large, it can not only effectively replace the initial stage of re-election beneficiation process, but also can be used as pre-sorting operation of some ore flotation. There are more than 60 non-ferrous and rare-metal beneficiation plants in the world adopting this advanced method.
