摘　　要：铼是一种稀散金属,在石油的催化裂化等方面有重要应用。铼在自然界中主要附生于辉钼矿和铜铼矿中,在冶炼过程中常随着废液流失。本文综述了近年来离子交换法、溶剂萃取法以及萃淋树脂法分离提取铼的研究进展,对不同分离方法的特点进行了分析,指出萃淋树脂法将离子交换和溶剂萃取两种技术结合起来,具有高选择性、环境友好等优点,可作为取代传统方法的新工艺。Rhenium,a precious rare metal,has been widely used in catalytic cracking of petroleum,aviation,and so on.However,it mainly distributes in Molybdenite and copper mines and always exists in the smoke and washing water produced in molybdenum concentrates roasting and leaching solution.Advances in the rhenium enrichment processes such as ion-exchange,solvent extraction and separation with Levextrel resins in recent years are reviewed in this paper.The application of Levextrel resins has advantages of ion-exchange and solvent extraction.It shows the potential to substitute for traditional processes.
