Definition and Importance of Gold Refining. Gold refining is the process of purifying raw gold of its impurities and unwanted elements like silver, copper, zinc and nickel. The goal of refining is to produce gold that is at least 99.5% pure, if not higher. Achieving higher purity levels through refining gives gold several important advantages.
