2020-10-12 How is gold and silver purified? Gold and silver are often extracted from the same ores and are chemically similar and therefore hard to separate. In the modern period chlorination using the Miller process, and electrolysis using the Wohlwill process are the most widely used methods of refining gold by removing silver and platinum.
