| Abstract: |
| Taking the rubidium-cesium extraction process as an example, the research situation of aluminum removal effect of extraction stock solution in pre-extraction process was introduced. In the production that has used extraction as the main process, if different extraction agents are added to remove aluminum, it will increase the complexity and cost of entire production line. It is believed that the chemical method should be used to remove aluminum in the extraction process. Therefore, on the basis of summarizing the previous methods of aluminum removal, the aluminum removal effect of complex solution system suitable for the extraction process in the industrial production of hydrometallurgy was studied. Through experiments on selection of aluminum removal reagents, the determination of pH range of aluminum removal, analysis of aluminum hydroxide precipitation and re-dissolution phenomena, removal characteristics of aluminum were investigated. The suggestions and ideas are put forward for application methods of aluminum removal treatment technology commonly used in hydrometallurgical industry. |
