| 中文摘要: |
| 采用硫代硫酸盐浸出脱铜阳极泥中的贵金属金、银和钯，研究氧化焙烧、碱预浸出和酸预浸出的预处理工艺对提高浸出率的影响。结果表明，3种预处理方式可在不同程度上降低硫、砷、锑、铅等元素对浸出效率的影响，采用氧化焙烧-酸预浸出-硫代硫酸盐浸出的方案，金、银和钯的浸出率分别达到了93.45%、96.32%和76.04%。 |
| 英文摘要: |
| The leaching process of precious metals, Au, Ag, Pd, from decopperized anode slime by thiosulfate has been investigated. Pretreatment processes including oxidizing roasting, alkaline leaching, acid leaching were optimized to improve the leaching efficiency of PMGs. The results showed that these three pretreatment processes can all minimize the effects of S, As, Sb and Pb on leaching efficiency, After the pretreatment of oxidizing roasting and acid pre-leaching, 93.45% of Au and 96.32% of Ag and 76.04% of Pd were leached out from the decopperized anode slime by thiosulfate. |
