| Abstract: |
| Three processes including refining with aqua regia, direct slag-making smelting, as while as silver replacement, nitric acid dissolving, and gold dissolving with aqua regia, were explored to treat aqua-regia-treated residue. The results show that residue of the first two methods needs retreating. Recovery rate of gold and silver of the third method is 99.97% above with the advantages of simple technological process and high recovery of gold and silver. |
