The C923 was employed to leach arsenic and bismuth in copper electrolyte with the purpose to observed influence of the extractant concentration, acidity,leaching time and phase ratio on the extraction rate to arsenic,moreover,the effect of chloride ion concentration on extracting bismuth was discussed as well.The results demonstrated that single-stage extraction rate of arsenic was approximately 68.41% in optimal conditions,and three cross-flow counter-current extraction rate was around 97.00%.However,when chloride ion concentration reached to 0.86 g/L,extraction rate of bismuth was about 95.15%.During the time when applying two cross-flow water with load phase to anti-extract arsenic,the total anti-extraction rate was 88.20%,nonetheless,using mixed solution of tartaric acid-sodium hydroxide to anti-extract bismuth,the result of anti-extraction rate was around 81.49%.

Key words: copper electrolyte, extraction method, arsenic, bismuth, C923 extraction regen
