Extraction of gold(I) cyanide by the primary amine tridecylamine

The extraction of gold(I) from cyanide solutions by tridecylamine/xylene solutions was studied at various temperatures, amine and metal concentrations. The influence of different diluents, aqueous ionic strength and the use of different mixtures of organophosphorous reagents and ketones with the amine in metal extraction was evaluated, and also the selectivity of the present extraction system. The gold-amine extraction mechanism is discussed.
