| Abstract: |
| Lead in waste lead paste was recovered classifiably with acid leaching, i.e., positive electrode was leached by acid in heating condition, and negative electrode was directly leached with acid. The results show that anode paste is fully reacted for 24 h with sulfuric acid of mass fraction of 85%(L/S=108 g/L), and conversion rate of PbSO4 is 91.34%. Positive paste material is treated with mass fraction of sulfuric acid of 85%(L/S=108 g/L) for 2 h at 65 ℃, and conversion rate of PbSO4 is 95.69%. Recovered PbSO4 can be used directly after electrolysis or desulfurization crystallization by sodium hydroxide. |
