江西某锂瓷土矿锂铷铯同步浮选实验
Experiment on Synchronous Flotation of Lithium-rubidium-cesium in a Lithium Porcelain Clay Mine in Jiangxi Province
摘要
Abstract
The Li2O grade of a lithium porcelain clay mine in Jiangxi Province is 0.46％.The lithium-containing minerals are mainly lithium muscovite,and the gangue minerals are mainly quartz,albite and potassium feldspar.In order to efficiently recover lithium-containing minerals from ores and maximize the comprehensive utilization of associated valuable elements such as rubidium and cesium,a systematic beneficiation experiment was conducted.The experimental results showed that at the grinding finness condition of-74 μm content 70.04％,after desliming,using self-developed high-efficiency collector TS-30,through a closed-circuit flotation process consisting of one roughing,one scavenging,and two cleaning,a mixed concentrate was ultimately obtained with Li2O,Rb2O,and Cs2O grades of 2.49％,0.78％,and 0.18％,respectively,and corresponding recovery rates of 81.30％,60.80％,and 69.79％.This approach achieved efficient recovery of lithium,rubidium,and cesium from the lithium clay ore.关键词
