【摘要】 本文研究了一种从废蓄电池泥渣中湿法回收铅的新工艺，该工艺以Ｋ＿２ＣＯ＿３脱硫，以自研的复合还原剂还原，以氟硅酸作电解液电冶Ｐｂ．获得铅粉纯度达９９．９９％，电流效率＞９８％，铅直收率＞９５％，铅总回收率＞９８％．此外，工艺过程稳定、效率高、成本低、无环境污染．更多还原

【Abstract】 This paper describes a new hydrometallurgical method for recovery oflead from waste battery sludge with K₂CO₃ as eliminating sulphur agent and the combi-nation reducing agent developed by us. Lead powder of 99. 99% pb was obtained by elec-trowinning with fluosolocic acid as electrolyte with current efficiency>98%. The directrecovery efficiency of pb from the sludge is higher than 95%and total pb recovery efficiency higher than 98%. Beside,the process presents stable reaction,high efficiencies,low cost and without environmental pollution.更多还原
