The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis. In this process, a casting of impure gold is lowered into an electrolyte solution of Elution Electrolysis System Prominer's Elution Electrolysis system is an integrated processing system striping gold from gold-loaded carbon under high-temperature high-pressure cyanide-free conditions. Developed from Zadra and AARL by raising elution temperature and replacing the atmospheric-pressure electrolysis cell with a pressure-bearing one and removing poisonous sodium

Gold and Platinum Refining Recovery Systems /

We perfected this process back in the late 80s for other refiners to refine both gold and platinum group metals safely, while also reducing costs. After working with people who have refined using this method, we've carefully perfected this method through the Simplicity Refining System to make it simple for individuals and companies.

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).
