摘　　要：这是一篇矿物加工工程领域的文章。研究对象为四川某锂辉石废石,根据该锂辉石废石的矿物特性,对该锂辉石废石三种不同入料粒度(-15+0.5 mm、-10+0.5 mm、-5+0.5 mm)分别进行实验室重液分选实验,实验结果表明,该锂辉石废石采用重液分选效果较好,且以-10+0.5 mm作为后续重介实验的入料粒度范围,并选择2.70 g/cm^(3)作为分选密度时,重液分选指标相对较好,但根据实际生产重介分选实验结果,最终在入选粒度为-15+0.5 mm,介质密度为2.0 g/cm^(3)时,分选指标相对较好。This is an article in the field of mineral processing engineering.The study objects are a spodumene waste rock in Sichuan.According to the mineral characteristics of thisspodumene waste rock,heavy medium separation tests were carried out at three different feed particle sizes(-15+0.5 mm,-10+0.5 mm,-5+0.5 mm)of the spodumene waste rock in laboratory.The test results show that the application of heavy medium separation in beneficiation of spodumene waste rock is very effective,and when-10+0.5 mm is used as the feed particle size range of the subsequent waste rock in heavy medium separation,and 2.70 g/cm^(3) is selected as the separation density,the results of heavy medium separation effect is relatively good.However,according to the actual production of heavy medium separation test results,the separation index is relatively good when the selected particle size is-15+0.5 mm and the medium density is 2.0 g/cm^(3).
