中文摘要: 针对金银冶金过程中铂钯的分布特点，提出了采用黄药富集分离、氯钯酸铵—二氯二氨络亚钯联合沉淀、水合肼还原的方法从银电解阳极泥中回收钯的新工艺。结果表明，所得海绵钯纯度大于99.95%，直收率大于97%。该工艺具有选择性分离钯效果好、过程无需赶硝、产品质量稳定等优点。
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.
