摘要:
为了进一步合理地开发利用川西措拉地区的锂辉石资源,以其锂辉石矿为主要研究对象,采用选择性较好的阴/阳离子组合捕收剂ST-8进行浮选试验研究。试验结果表明:在磨矿细度为-0.074 mm占77.2%下,采用一次粗选三次精选一次扫选中矿顺序返回的闭路流程。粗选Na2CO3用量1 000 g/t加入磨机中,NaOH、CaCl2和组合捕收剂ST-8用量分别为700、80、2 000 g/t;在精选中,精选Ⅰ、精选Ⅱ和精选ⅢNa2CO3用量分别为800、400、200 g/t;扫选中NaOH和组合捕收剂ST-8用量分别为100、500 g/t;最终得到锂辉石精矿品位为6.34%,精矿回收率为88.51%,得到较好浮选指标。试验说明采用阴/阳离子组合捕收剂能有效浮选低品位锂辉石。
Abstract:
To further rationally develop and utilize spodumene resources in the Cuola area of western Sichuan, the spodumene ores there was taken as the main research objects, and a flotation test was carried out using the highly selective anion/cation combined collector ST-8. The test results showed that with a grinding fineness of -0.074 mm accounting for 77.2%, a closed circuit process consisting of one roughing, three cleanings, and one scavenging with sequential middling return was adopted. For the roughing, 1 000 g/t of Na2CO3 was added into the mill, and the dosages of NaOH, CaCl2, and the combined collector ST-8 were 700, 80 and 2 000 g/t, respectively. In the cleanings, the dosages of Na2CO3 in cleaning Ⅰ, Ⅱ, and Ⅲ were 800 g/t, 400 g/t, and 200 g/t respectively. For the scavenging, the dosages of NaOH and the combined collector ST-8 were 100 g/t and 500 g/t, respectively. Eventually, a spodumene concentrate with a grade of 6.34% and a recovery rate of 88.51% was obtained, achieving good flotation indexes. The test indicated that the anion/cation combined collector can effectively float low grade spodumene.
