摘要
An extraction component enabling the concurrent recovery of gold and/or palladium selectively from a hydrochloric acid media containing the base metals and other contaminants. The disclosed extractant disclosed eliminates the conventional multi-step process for such extraction by providing for an extraction method which uses a single solvent extraction reagent. Further enhancing the conventional multi step process, the conventional scrubbing stage is eliminated by a single stripping stage. The resulting solutions can be obtained from leaching many types of material such as copper anode slimes, the treatment of scrap such as electronic circuit boards and plating effluents, PGM, or refractory gold ores.
