摘要：
Rhenium is an important strategic resource due to its wide potential applications in the fields of national defense, aerospace and new high technologies. The content of rhenium in the Earth crust is very low, as a dilute metal. The simple and efficient separation and enrichment method is very important for the exploitation and utilization of rhenium. Here, the process flows of rhenium metal smelting and recovery process and the progress in recent years were reviewed in terms of their advantages and disadvantages. The method of rhenium enrichment and separation which had been studied and applied at present, such as organic solvent extraction, ion exchange, resin extraction, emulsion extraction and adsorption, were reviewed. The new adsorption materials including bulky materials, nano-materials, biomass materials and mesoporous silicon materials and their applications were preferably introduced for the enrichment and separation of rhenium by aiming at the development and recovery of rhenium primary and secondary resources. Finally, the new direction of enrichment and separation of rhenium and the new characteristics of technology was prospected. © 2020, Science Press. All right reserved.
