Flash furnace electrostatic precipitator dust (FF-ESP dust) is a recycle stream in some primary copper production facilities. This contains high amounts of copper. In cases, the FF-ESP elevated levels bismuth and arsenic, both which cause problems during electrorefining stages production. Because this, methods for separation from arsenic are necessary. Hydrometallurgical leaching using number l...
Ion exchange has been widely applied in technology of chemical separation of noble met‐ al ions. This is associated with dissemination of methods using various ion exchange res‐ ins which are indispensable in many fields of chemical industry. Due to small amounts of noble elements in nature and constant impoverishment of their natural raw materials, of particular importance are physicochemical ...
