摘要
铼作为一种稀散金属,在铜双闪速悬浮熔炼过程中分散在各种副产物中,其在污酸和砷滤饼中的富集度较高,人们可以通过氧化焙烧、高压浸出、离心萃取等工艺流程对铼金属进行有效回收。
As a rare metal,rhenium is dispersed in various by-products during the copper double flash suspension smelting process.The enrichment degree in the sulphuric acid and arsenic filter cake is high,and the rhenium can be effectively recovered by oxidation roasting,high pressure leaching,centrifugal extraction and other processes.
