摘要
Gold extraction from alkaline aurocynide solution (about 10 mg/L) with 100% TBP in aqueous phase with CTAB and without CTAB,was studied.The effect of NaCl concentration,initial gold concentration in organic phase,equilibrium isotherm and the changes of extraction rate with extraction times were investigated.The results show that 100% TBP has better extraction characteristic in aqueous phase with CTAB than in aqueous phase without CTAB.The results of extraction from 10 L gold alkaline aurocynide solution of 10 mg/L using 150 mL TBP indicate that gold extraction rate is more than 90%.
