尽管大家对重介质分选(HMS)已熟知了一段时间,但是,直到现在,这一通用技术的应用仍没有引起矿业界的重视。应该指出的是,随着基本投资和操作费用的增加,以及对环境问题的关注,重介质分选概念在将来应该给矿业带来巨大的效益。在高能耗、高费用的磨矿作业之前,对粗碎过的金属矿物和工业矿物进行预先富集,可以预先抛弃3 0 %～70 %的尾矿。因此,减少了进入昂贵的磨矿、随后的浮选或浸出作业的给矿量。这一包括有预选概念的流程可以大大改善矿山的经济效益。从现在的技术、经济和环境方面来看,这一效果为重介质分选在金属矿物和非金属矿物领域应用展现了美好的前景
Although everyone has been familiar with HMS for some time, the application of this common technology has so far failed to draw the attention of the mining industry. It should be pointed out that the concept of heavy medium separation should bring tremendous benefits to the mining industry in the future as the cost of basic investment and operation increases and the environmental concerns are raised. Prior to high-energy, high-cost grinding operations, coarsely crushed metal and industrial minerals are pre-enriched to pre-reject 30% to 70% of the tailings. As a result, the amount of ore fed into expensive grinding, subsequent flotation or leaching operations is reduced. This process, including the concept of pre-selection, can greatly improve the economic benefits of mines. From the current technical, economic and environmental perspective, this effect shows a promising future for the application of HM separations in the field of metallic and non-metallic minerals
