Abstract
The process for treating sulphated lead compounds, more particularly those coming from exhausted storage batteries, comprises the steps of subjecting said sulphated compounds to leaching (12) with sodium carbonate in aqueous solution, collecting on a filter (15) the lead carbonate thus obtained from the sodium sulphate which is left dissolved, subjecting the lead carbonate to reduction (18) to metallic lead, separating the sodium sulphate by crystallization (22) from the filtrates (21) and recycling the mother liquors (23) of crystallization to the leaching stage (12).
