摘　　要：针对四川某锂辉石矿的矿石性质,采用碱法不脱泥工艺进行了锂辉石与脉石的分离。探索了调整剂用量和作用时间对锂辉石浮选的影响,结果表明,氧化石蜡皂与另外两种阴离子捕收剂组合而成的新型组合捕收剂OPS-3对浮选锂辉石具有较好的选择性和捕收能力。采用OPS-3进行闭路试验,最终得到Li2O品位为5.86%、回收率为81.30%的锂辉石精矿。After studying the ore properties of a to separate spodumene and gangues in alkaline on spodumene flotation were investigated, and mixing oxidized paraffin soap with other two capacity. The closed-circuit test with OPS-3 as recovery of 5.86% and 81.30%, respectively. spodumene mine in Sichuan, a direct flotation technology was introduced pulp without desliming. The effects of regulator dosage and reaction time the results show that, OPS-3, a new combined collector prepared by common anionic collectors, shows improved selectivity and collecting the collector resulted in a spodumene concentrate with Li20 grade and
