摘　　要：随着金矿石品位下降、浅部资源日益枯竭和采选成本增加,越来越多的黄金矿山企业和科研机构开始关注低品位金矿石的高效分选工艺。采用适合的工艺对低品位原矿进行预选抛尾,可以有效提高矿石入选品位,减少提升和破磨的矿石总量,提高设备利用率,在增产降耗和环境保护等方面均能起到积极的作用。With the decline of gold ore grade,the depletion of shallow resources and the increase of mining cost,more and more gold mining enterprises and scientific research institutions began to pay attention to the high efficiency separation process of low grade gold ores.Using suitable technology to preconcentrate discarding Tailings of low-grade raw ore can effectively improve the ore grade,reduce the total amount of ore raised and broken,improve the equipment utilization rate,and play a positive role in production increase and consumption reduction and environmental protection.
