摘　　要：为了寻找选择性好、捕收能力强的脱硫捕收剂,针对四川某锂辉石矿酸法提锂后产生的副产品锂渣,进行了多种组合捕收剂的浮选脱硫探究试验。结果表明:采用LS+JFCG质量比为4∶1的组合捕收剂,当用量为150 g/t时,经1粗3扫2精闭路浮选工艺流程,可获得SO_(3)品位0.53%的锂渣精矿,同时获得了SO_(3)品位42.56%的石膏,达到了锂渣高效脱硫的目的,为锂渣高值化综合利用创造了条件。In order to find a desulfurization collector with good selectivity and strong collecting ability,the flotation desulfurization test of various combined collectors was carried out for the by-product lithium slag produced by the acid extraction of lithium from a spodumene ore in Sichuan.The results showed that through the closed-circuit flotation process of one roughing,three scavenging and two cleaning,the lithium slag concentrate with SO_(3) grade of 0.53%and gypsum with SO_(3) grade of 42.56%could be obtained by using the combined collector of LS+JFCG mass ratio of 4∶1 and the dosage of 150 g/t.The purpose of efficient desulfurization of lithium slag is achieved,which creates conditions for the high-value comprehensive utilization of lithium slag.
