摘　　要：对湖南某Li_(2)O和Rb_(2)O品位分别为0.27%和0.17%的低品位含铷锂云母矿进行了选矿试验研究。采用脱硫-选锂浮选流程,使用高效捕收剂CK与十二胺组合作为锂捕收剂,在弱碱性条件下,闭路试验获得了Li_(2)O品位2.71%、Rb_(2)O品位1.02%,回收率分别为86.34%、51.24%的锂精矿指标,达到了低品位锂云母矿高效利用的目的。A mineral processing test was conducted to treat a low-grade rubidium-bearing lepidolite ore from Hunan Province with the grade of Li_(2)O and Rb_(2)O respectively at 0.27%and 0.17%.A flowsheet including a desulphurization and a lithium flotation was adopted,and an efficient collector CK was used in combination with dodecylamine to collect lithium minerals under weak alkaline conditions.In a closed-circuit test,a lithium concentrate was produced with Li_(2)O grade and recovery of 2.71%and 86.34%,Rb_(2)O grade and recovery of 1.02%and 51.24%,respectively.It is concluded that efficient utilization of low-grade lepidolite ore can be actualized.
