Selective recover of bismuth by amide extractant from chloride leaching of lead anode slime and the mechanism

Key Points

• Selective recovery of bismuth is achieved through an amide extractant during chloride leaching, showing high efficacy.
• The mechanism involves specific interactions between the extractant and bismuth ions, optimizing recovery rates.
• Laboratory experiments confirmed the successful extraction of bismuth over other metals present in lead anode slime.
• Significance lies in developing efficient methods for resource recovery and treating industrial byproducts.
