摘要
铼元素是一种可广泛应用于国防、航空航天以及新型科技领域的重要战略资源。铼元素在地壳中含量极低,是一种稀散金属,需要通过高效的分离富集才能获取。介绍近年来铼金属的冶炼/回收工艺流程及进展,综述近年来铼金属的冶炼/回收工艺流程及其进展,重点介绍可应用于铼富集分离的块体材料、纳米材料、生物质材料、介孔硅材料等新型吸附材料及其在铼一次资源与二次资源的开发与回收中的应用,并对铼富集与分离技术的发展进行展望。
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.
