The extraction of gold from alkaline cyanide solution by alkyl-substituted secondary amine has been investigated. The effects of several variables, such as equilibrium time, temperature, diluent, extractant concentration, pH, gold concentration, ionic strength of the aqueous phase and phase ratio (O/A) on the extraction yield are discussed. The extraction isotherm, saturation capacity, separation coefficients of gold to silver (Ⅰ), ferrous (Ⅱ), copper (Ⅰ), nickel (Ⅱ), zinc(Ⅱ) have been determined respectively. Stripping extraction of gold from loaded organic phase has also been studied. The results showed that the system consisted of 0.1%(volume fraction) secondary amine(7203)-0.05% (volume fraction)ROH-n-dodecane gave high extraction yield and selectivity for Au(CN)₂ at pH_1/2=11.7.
