| Abstract: | 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. |
