稀散金属铼资源综合回收利用研究进展

Research Progress on Comprehensive Recovery and Utilization of Rhenium Resources

  • 摘要: 铼是地球上一种极其稀散的贵金属,常赋存在辉钼矿和斑铜矿等矿物中,在航空航天、石油催化等领域有十分重要的作用。目前,从钼精矿中提铼是最常见的回收铼资源的方法之一。文章概述了从钼精矿中提铼的工艺,主要包括全湿法工艺以及火法焙烧—湿法浸出联合工艺,同时介绍和总结了含铼溶液分离提取铼的方法,主要有化学沉淀法、离子交换法、溶剂萃取法和萃淋树脂法等,最后对铼资源的综合回收利用发展方向进行了展望。

     

    Abstract: Rhenium is a rare precious metal on the earth. It is often found in molybdenite, porphyry and other minerals. It plays a very important role in the fields of aerospace and petrochemical industry. At present, one of the most important methods to recover rhenium resources is to extract rhenium from molybdenum concentrates. In this paper, the process of rhenium extraction from molybdenum concentrate is summarized, which including the whole wet process and the combined process of calcination and wet leaching. Meanwhile, the separation and extraction method of rhenium in solution containing rhenium is introduced and summarized. Finally the development direction of the comprehensive recovery and utilization of rhenium resources is prospected.
