哈萨克斯坦是有色金属的主要生产国。重金属的生产通常基于火法冶金工艺，从而产生含有稀有金属的副产品，特别是重金属。回收铜的基本矿物原料是铜、铅和铀生产的固体和液体副产品。在含铜的硫化铜精矿的火法冶炼过程中，这种金属浓缩在冶金气体中。在气相净化过程中，硫酸盐分布在粉尘、泥渣和洗涤硫酸之间。粉尘被送到铅冶炼厂，从铜生产的洗涤硫酸中回收铅。铀矿地下浸出过程中获得的溶液可以成为商业生产铅的新来源，尽管浓度很低。本文介绍了采用浸出、离子交换、溶剂萃取、电渗析等方法从铜、铅、铀生产副产品中回收铅的工艺流程。(C)2011 Elsevier B.V.保留所有权利。
Kazakhstan is a major producer of non-ferrous metals. The production of heavy metals is generally based on pyrometallurgical processes resulting in the generation of by-products which contain rare metals, in particular rhenium. The base mineral raw materials for recovery of rhenium are solid and liquid by-products of copper, lead and uranium production.In pyrometallurgical processing of sulfide copper concentrates containing rhenium, this metal is concentrated in metallurgical gases. During the purification of the gas phase, rhenium is distributed between dusts, slime and wash sulfuric acid. Dusts are sent to lead smelters, and rhenium is recovered from wash sulfuric acid of copper production.Solutions obtained during underground leaching of uranium ore could be a new source for commercial production of rhenium despite low concentration. In the paper presented technological flowcharts for recovery of rhenium from by-products of copper, lead and uranium production with application of leaching, ion exchange, solvent extraction and electrodialysis.
