摘要:

铼是一种关系国家工业生产及科技发展的战略性金属元素,在自然界中含量低且分散,主要伴生于钼、铜、铅和铀精矿中。 铼从焙烧烟尘、浸出残渣或水溶液中提取,制成含铼溶液。 随后,通过离子交换、液膜分离、溶剂萃取、吸附法等富集技术生成富铼溶液。 最后,通过结晶、冷却和还原等步骤生产铼。 此外,由于铼资源的稀缺,从废弃的合金和催化剂等二次资源中回收铼也受到广泛关注。

Abstract：

Rhenium is a strategic metal element related to national industrial production and scientific and technological development. It is low and dispersed in nature and is mainly associated with molybdenum, copper, lead and uranium concentrates. Rhenium is extracted from roasting dust, leaching residue or aqueous solution to produce rhenium-containing solution. Subsequently, rhenium-rich solution was formed by ion exchange, liquid membrane separation, solvent extraction, adsorption and other enrichment techniques. Finally, rhenium is produced by crystallization, cooling and reduction. In addition, due to the lack of rhenium resources, the recovery of rhenium from secondary resources such as waste alloys and catalysts has also attracted widespread attention.
