[China's characteristic lithium ore associated rubidium and cesium resources have achieved new breakthroughs in efficient green separation technology] September 9th, recently, the world's first 500-ton annual continuous tower extraction and separation of characteristic lithium ore associated with low-grade rubidium and cesium demonstration line was built by the Institute of Process Engineering of the Chinese Academy of Sciences, Ganfeng Lithium Industry and others. The whole process has been stably operated at full capacity. The purity of the products cesium carbonate and rubidium carbonate has reached over 99.9%, and has been put on the market. The full-scale operation of this demonstration line marks an important breakthrough in China's efficient and green separation technology of low-grade associated rubidium and cesium resources, providing a solid guarantee for the efficient and green utilization of China's rubidium and cesium resources.
