摘要
对贵金属富集、精炼工艺中大量、低量和微量铜的分离方法作了简要的归纳和分析。贵金属富集工艺中大量铜的分离方法包括硫酸化焙烧法、氧化焙烧法、硝酸溶解法、稀硫酸选择氧化溶解法、控制电位氯化法等。贵金属精炼工艺中低量或微量铜的分离方法包括萃取法和离子交换法。
The macro?low and micro-copper separation in the precious metals concentrating and refining technology have been briefly reviewed and analysised.The main methods of the macro-copper separation in the precious metals concentration technology is sulfuric acid roasting,oxidation roasting,nitric acid resolution,diluent sulfuric acid oxidation resolution selectivity,and control potential chlorination.The methods of the low and micro-copper separation in the precious metals refining technology is solvent extraction and ion exchange.The advantage,disadvantage and application field of various methods have been also given.
