四川某大型锂辉石矿床矿石风化严重，含泥量大，常年温度偏低，导致生产现场锂辉石选别困难，回收率偏低，为有效回收该矿产资源中的锂矿物，对其进行了选矿试验研究。结果表明，采用沉降脱泥方案进行预先脱泥，配合添加高效混合捕收剂YHZ浮锂，在原矿Li2O品位1.47%的条件下，经1粗2扫3精、中矿顺序返回的浮选闭路试验获得Li2O品位6.12%、回收率86.01%的锂精矿。试验结果为生产现场进行流程改造提供了技术依据。

A large-scale spodumene ore deposit from Sichuan was in low temperature of the whole year, the ore was seriously weathered and contained high amounts of mud, it was very dififcult for dressing in production ifeld and it had low recovery rate of Li2O. Beneifciation process were made on this spodumene ore to effectively recover the valuable minerals. The results showed that, adopting the technical conditions of settlement desliming process before flotation, a new special combined collectors YHZ was added in flotation, the closed circuit flowsheet by one stages of roughing,two stages of cleaning and three stages of scavenging for lfotation of Li and returning of middling in turn. Then, concentrate with Li2O grade of 6.12% at a 86.01% Li2O recovery was achieved which based on the raw ore contained Li2O 1.47%. The lfotation results provided the technical foundation to reform the production process.
