HYDROMETALLURGIC PROCESS FOR RECOVERING IN THE METAL FORM THE LEAD CONTAINED IN THE PASTE OF THE EXHAUSTED BATTERIES |
| 摘要 |
<p>The desulphurized paste is leached with an acid suitable for the subsequent electrowinning, with an amount of hydrogen peroxide necessary to reduce all of the existing PbO2 being added. A high extraction yield is obtained, without foreign salts being added to the electrolyte, which is then submitted to an electrolysis step, to recover Pb as cathodes. <IMAGE></p> |
