一、前言 江西宜春锂云母精矿除含丰富的锂外,还有较多的铷,铯、钾等有用元素。继石灰石烧结法提取锂盐的研究完成后,我们又研究了从提锂母液提取钾(钠)、铷、铯的工艺流程。提取了纯度>95％的碳酸氢钾、纯度>95％的氯比铯以及纯度>85％的氯化铷。达到了综合利用的目的。 I. Preface Jiangxi Yichun Lithium Mica Concentrate contains abundant elements such as rubidium, cesium and potassium besides abundant lithium. Following the completion of the research on lithium salt extraction by limestone sintering, we also studied the technological process of potassium (sodium), rubidium and cesium extraction from the extraction of lithium mother liquor. Potassium bicarbonate> 95% purity, cesium chloride> 95% purity, and rubidium chloride> 85% purity were extracted. Achieve the purpose of comprehensive utilization.
