摘　　要：为解决脂肪酸类捕收剂浮选锂辉石时选择性差、泡沫黏稠、药剂用量大的问题,进行了阴、阳离子捕收剂浮选锂辉石、石英、长石的试验研究。结果表明,阴离子捕收剂和阳离子捕收剂组合可以增加药剂组分间的协同作用,提高精矿品位或回收率。以阴、阳离子捕收剂组合的CFLH-18为捕收剂对四川金川某花岗伟晶岩型锂辉石矿进行浮选闭路试验,获得了Li_(2)O品位4.62%、回收率78.54%的锂辉石精矿,与现场脂肪酸类捕收剂生产指标相比,锂辉石精矿Li_(2)O品位提升了0.10百分点,回收率提升了5.93百分点,精矿富集比从3.77提高到了4.57。To solve problems of poor selectivity,thick foaming and large reagent consumption in recovering spodumene with fatty acid collectors,anionic and cationic collectors were introduced to flotation tests of spodumene,feldspar and quartz.According to the results of pure mineral tests,a anionic-cationic collector can enhance the synergistic effect of reagents,and improve the grade and recoveries of concentrates.CFLH-18,a combination of anionic and cationic collectors,was introduced in a close-circuit flotation test of granite pegmatite-type spodumene from Jinchuan County of Sichuan Province,and a spodumene concentrate with Li_(2)O grade of 4.62%was collected at 78.54%recovery.Compared with the on-site practice using fatty acid collectors,Li_(2)O grade and recovery are improved by 0.10 percentage points and 5.93 percentage points.Meanwhile,the concentrate enrichment ratio is raised from 3.77 to 4.57.
