| Abstract: |
| According to the distribution characteristics of platinum and palladium in gold and silver metallurgical process, an new technology for recovering palladium from silver electrolytic anode mud by selective enrichment and separation with C4H9OCSSNa, (NH4)2PdCl6—Pd(NH4)2Cl2 joint precipitation, and hydrazine hydrate reduction was presented. The results show that the purity of product sponge palladium is more than 99.95%; the direct recovery rate is over 97%. This process has the advantages of good selective separation of palladium, no removing nitrate in the process and stable quality of product. |
