The invention refers to a procedure of lead salvage from usedaccumulators sulphated paste by treating with an alkaline solution,at weight liquid-solid ratio of 6:1 at 80 0 C. The resulted solution issubjected to re precipitation with sulphuric acid, and resulted PbSO 4is dissolved in ammoniacal environment, at 60 0 C and at weightliquid-solid ratio of 3:1.Invenţia se referă la un procedeu de recuperare a plumbului dinpasta sulfatată a acumulatorilor uzaţi prin tratare cu o soluţiealcalină, la un rapot, în greutate, lichid: solid 6:1, la 80 0 C. Soluţiarezultată se spune reprecipitării cu acid sulfuric, iar PbSO 4 rezultateste solubilizat, în mediu amoniacal, la o temperatură de 60 0 C şi laun raport, în greutate, lichid: solid de 3:1.32
