Abstract
The extraction of Au(III) with the extractant trioctylmethylammonium c hloride (TOMACl) dissolved in toluene and the same extractant impregna ted in a polymeric resin XAD-2 has been studied, The results of gold e xtraction with both systems were compared. They showed similar gold ex traction behaviour (extracted species), although greater amounts of ex tractant were needed when impregnated resins were used, Liquid-liquid and solid-liquid procedures can be used to extract gold selectively fr om solutions containing zinc and copper.
