Spent lead acid batteries are a rich source for the production of secondary lead. Pyrometallurgical operation currently practised exploiting this resource produces a lot of emission of oxides of sulphur and lead particulates causing atmospheric pollution. This paper examines an alternative approach for the extraction of lead avoiding environmental hazards. Lead in the compound form is not amenable for recycling to a large extent. This investigation is concerned particularly with recovery of lead from non-metallic portion of the spent battery plates viz. lead sulphate and lead dioxide of active material. Lead was extracted as fluoborate and aspects like desulphurisation, reduction and leaching were examined for maximum recovery. Finally lead was electrowon from the lead fluoborate solution
