A process for the recovery of lead from spent battery paste and lead containing materials. The process includes the steps of calcination of a spent paste treated with an alkali carbonate or hydroxide or any mixture thereof, and elemental sulphur at a temperature of up to 600 DEG C., followed by washing with water. The calcined and washed paste is dissolved in an alkali molten electrolyte, and lead is electrowinned from the alkali molten electrolyte. The spent electrolyte is reused in the process.
