摘要
铼在自然界多以微量元素伴生于钼、铜、铅等矿物中。在钼精矿焙烧过程中,铼主要以氧化物形式挥发进入烟尘,钼精矿焙烧副产物烟灰是回收铼的二次资源原料。评述了钼精矿焙烧烟尘中铼的回收研究进展,重点介绍了烟灰中的铼浸出工艺和含铼溶液中铼的富集方法。
Rhenium is mostly associated in minerals of molybdenum,copper and lead with trace elements.During roasting process of molybdenum concentrate,rhenium is volatilized into dust in form of oxides.Roasting dust as by-product of molybdenum concentrate roasting is the secondary resource material to recover rhenium.Recent progress in recovery of rhenium from roasting dust of molybdenum concentrates is reviewed.Leaching of rhenium from roasting dust and enrichment of rhenium in rhenium-bearing solution are introduced.
