Extraction of Rubidium,Cesium and Lithium from Lithium Mica Ore by Chlorination Roasting-Water Leaching Process AITranslate
Abstract AITranslate
Taking lithium mica ore as the research object,the exploration experiments of sulfuric acid curing-water leaching,fluorinating acid leaching,calcium carbonate roasting-water leaching,calcium sulfate roasting-water leaching and chlorination roasting-water leaching were carried out.It is determined that the chlorination roasting-water leaching process at room temperature is more suitable for the comprehensive extraction of rubidium,cesium and lithium from lithium mica ore.Meanwhile,the effects of roasting temperature,roasting time,additive type and dosage,leaching liquid-to-solid ratio,and leaching temperature on the leaching rates of rubidium,cesium and lithium were also investigated.The results show that under the conditions of calcium chloride dosage of 50%,sodium carbonate dosage of 20%,roasting temperature of 750℃,roasting time of 6 h,and leaching liquid-to-solid ratio of 1∶1,more than 95%rubidium,94%cesium and 87%lithium could be leached after the process of chlorination roasting and water leaching at room temperature for 1 h.At the same time,sodium carbonate absorbs the chlorine gas released from calcium chloride during the roasting process,and the process has little environmental pollution.
