Electrolytic Refining Process. This process is using for obtaining ultra pure precious metals such as 99,999 Gold and 99,99 Silver etc. Under proper process conditions, the electrons of precious metals go to cathode from anode. By this way, impurities can remove from the precious metals.Precious Metal Refining Process | The 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).A study of certain problems associated with the,,Metal of high purity is required for many industrial applications of gold.
