为综合回收某热液蚀变型黏土锂矿中的石英和锂，开展了选冶联合提锂试验。原矿矿物成分主要为长石、石英、绿泥石、白云母，含Li2O 0.214%。采用制砂—擦洗—脱泥—磁选—浮选工艺流程回收石英，获得产率为8.45%、SiO2品位为99.16%的石英精矿，以及产率为5.02%、SiO2品位为95.43%的石英次精矿，锂主要富集于泥质矿物、弱磁性矿物和浮选尾矿中。采用硫酸熟化—水浸工艺进行提锂，适宜的工艺条件为：酸矿比1.5∶1、熟化温度160℃、熟化时间4.0 h、酸浓度60%、水浸液固比2∶1、水浸时间1.0 h，在此条件下，泥质矿物、弱磁性矿物和浮选尾矿中锂的浸出率分别为98.40%、91.21%、83.75%，锂的综合浸出率为93.67%。
