| 中文摘要: |
| 钌蒸馏渣中贱金属的稀硫酸直接浸出率低，渣中的铂溶解率低，回收困难。采用焙烧研磨、还原预处理后，贱金属易被浸出；富集在硫酸浸出渣中铂易被王水溶解(溶出率99%)，物料中的钌在渣中也得到富集；铂溶液经氯化铵沉淀煅烧得到粗铂；粗铂溶解后经多次氧化水解除杂、氯化铵沉淀法精炼，得到99.99%的海绵铂产品，铂回收率98.07%。 |
| 英文摘要: |
| Using dilute sulfuric acid to directly leach ruthenium distillation residue, the leaching rates of base metals and platinum are low, which leads to difficulty in platinum recovery. After roasting, grinding and reduction pretreatment, the base metals are easily leached. Platinum enriched in the sulfuric acid leaching residue can easily be dissolved in aqua regia, and the dissolution rate is 99%. Ruthenium is also enriched in aqua regia leaching residue. The obtained platinum-containing solution is precipitated by ammonium chloride and then calcined to obtain crude platinum. After the crude platinum is dissolved, it is purified by repeated oxidation hydrolysis and ammonium chloride precipitation refining to obtain a sponge platinum product with a purity of 99.99%, and the platinum recovery rate reaches 98.07%. |
