Study on Bismuth Extraction from Antimony Bismuth Slag by Leaching
Based on the composition of antimony bismuth slag,the effects of chloride ion concentration,acidity,liquid-solid ratio,and reaction time on bismuth leaching from antimony bismuth slag were experimentally studied.The optimal conditions were found to be chloride ion concentration of 85 g/L,acidity of 120 g/L,liquid-solid ratio of 10:1,and reaction time of 2 hours,which also facilitated the recovery of bismuth resources from antimony bismuth slag.
