Research on Rubidium and Cesium Resources,Extraction Technology,Development,and Utilization in China
Rubidium and cesium have excellent physicochemical properties and are widely used in traditional applications,including electronic devices,catalysts,and special glass,and emerging high-tech applications.Cesium and rubidium resources in China are relatively abundant and of various types,including solid and liquid minerals.This study focused on domestic rubidium and cesium resources,extraction technology and characteristics,and the current situation of resource development and utilization.Domestic rubidium-cesium resources are primarily solid ores,with reserves of rubidium and cesium in the forms of Rb2O and Cs2O amounting to 1.16 million and 140 000 tons,respectively.The extraction of rubidium-cesium from solid ores using the acid method has been industrialized,and the extraction and ion-exchange methods hold promise for liquid ore application.Recently,the rubidium mine,in Tiantangshan,Guangdong Province,a development project has attracted increasing attention.Rubidium and cesium resources in salt lakes and underground brines have more development potential,indicating the need to strengthen domestic rubidium-cesium resource investigation,surveys,comprehensive extraction technology research and development for low-grade solid and liquid ore resources,and broadening the rubidium-cesium products regarding new performance and application areas.
