低品位矿石预选抛废技术研究及工业化应用

Research and industrial application of low grade ore pre concentration and discarding waste technology

某矿山因高品质氧化锡矿和锡铜硫化矿资源逐渐消失,低品位矿石量增加,生产成本较高,从而开展了预选抛废技术研究及工业化应用,原矿制备作业预选抛除废石,富集并提高入选品位,降低选矿成本。

Due to the gradual disappearance of high-quality tin oxide ore and tin copper sulfide ore resources in a mine,the amount of low-grade ore increases and the production cost is high.Therefore,the pre concentration and discarding waste technology research and industrial application are carried out.The raw ore preparation operation pre concentration discards the waste rock,enriches and improves the beneficiation grade,and reduces the beneficiation cost.
