摘要
铼是典型的稀散金属,自然界没有固定的矿物,主要从铜、钼加工"三废"———烟气、烟道灰及浸出废液中回收和提取。本文总结了十余年铼回收工作实践中对钼焙烧铼回收工艺中逸出、吸收、净化、提取等几个关键问题的认知和解决方法,以促进钼焙烧烟气铼回收的推广和钼焙烧清洁生产工艺的进步。
Rhenium is a typical rare dissipated metal. It doesnt have stationary mineral and is mainly recovered and extracted from the flue gas, the flue dust and the leaching liquid waste of copper and molybdenum. This article summarizes the understanding and solutions on the spill,absorption,purification and extraction in the process of rhe- nium recovery from molybdenum roasting flue gas with practice experience, in order to boost the promotion of rheni- um recovery from molybdenum flue gas, and the progress of the cleaning production of molybdenum roasting.
