  • Gold And Silver Refining Explained - Perth Mint

    The electrolytic silver refining process is similar to gold, except that the silver anodes are dissolved in a bath of nitric acid. The resulting cathodes are 99.9% pure silver. As with small gold bar production, these cathodes are melted, granulated and cast into retail sized bars (most common being 100oz or kilo).
