摘要：

The extraction of gold(I) from cyanide solutions using the primary amine Primene 81R has been studied taking into account the variables temperature, agitation time, metal and amine concentration and aqueous ionic strength. The results show that gold(I) is extracted by means of a complex with the possible stoichiometric formula: [RNH3+Au(CN)2-.3RNH2]org. The infrared spectrum shows that there is no specific interaction between the amine and the cyanide gold complex.
