摘要:

贵州某锂绿泥石为典型黏土型锂矿,以该矿石为研究对象,对其进行焙烧—浸出试验研究。考察磨矿细度、焙烧温度、焙烧时间、浸出温度、浸出时间、振荡频率及浸出液固比对锂浸出率的影响。研究结果表明:在磨矿细度为-0.038 mm占89 %,硫酸用量为0.8 kg/t、焙烧温度为400 ℃、焙烧时间为1 h,浸出温度为80 ℃、浸出时间为1 h、振荡频率为150 r/min、浸出液固比4∶1的条件下,锂浸出率为97.31 %,浸出效果较好,对该锂绿泥石开发利用具有重要意义。

Abstract:

A cookeite in Guizhou is a typical clay type lithium ore and was selected as the research object for a study on roasting-leaching experiments.The effects of grinding fineness,roasting temperature,roasting time,leaching temperature,leaching time,oscillation frequency,and liquid-solid ratio on lithium leaching rate were investigated.The results showed that under the conditions of grinding fineness of -0.038 mm accounting for 89 %,sulfuric acid dosage of 0.8 kg/t,roasting temperature of 400 °C,roasting time of 1 h,leaching temperature of 80 °C,leaching time of 1 h,oscillation frequency of 150 r/min,and liquid-solid ratio of 4∶1,the lithium leaching rate reached 97.31 %.The leaching effect was excellent,and this study has significant implications for the development and utilization of the cookeite.
