Silver Refining. The composition of silver doré bars The Perth Mint processes are composed of around 90% silver and 10% gold. As with gold doré, the silver doré is weighed, melted, assayed and outturned. The electrolytic silver refining process is similar to gold, except that the silver anodes are dissolved in a bath of nitric acid.
