The application possibilities of gold(I) extraction from cyanide media by three primary amines, Primene 81R, Primene JMT and tridecylamine, has been studied taking in account several variables such as temperature, amine and initial metal concentrations, aqueous ionic strength and organic phase diluent; the selectivity of the extraction systems is also described. On the basis of graphical and numerical treatment an extraction mechanism for gold has been proposed
