Solvent extraction of aurocyanide from alkaline cyanide solution with five extractants:amide(N₅₀₃), secondary amine(7203), tri-alkylguanidine(Lix7825), quaternary ammonium chloride(N₂₆₃) and tributyl phosphate(TBP) has been studied. The factors that could effect the extraction of the metal such as equilibrium time, aqueous pH, saturation capacity, separation factors of gold and silver(Ⅰ), ferrous(Ⅱ), copper(Ⅰ), nickel(Ⅱ), zine(Ⅱ) are discussed and determined. The order of extraction ability of the five extraction systems for aurocyanide from alkaline cyanide solution as follows: N₂₆₃> Lix7825> 7203> N₅₀₃> TBP, same as the alkalinity order of the extractants, but in a reverse order to the selectivity and saturation capacity for aurocyanide. The above results have been proved in the case of synthetic solution in a single extraction and leach liquors of a gold concentrate in three stages contiuous extraction.
