Nov 28, 2016· Electrolysis is also widely used in the production and refining of precious metals, for instance, electrolytic gold is produced using hydrochloric acid as an electrolyte, known as the Wohlwill process, which produces gold at 99.5% purity. Further electro-refining using the Miller chlorination process can improve gold's purity to 99.999%.

Zone melting - Wikipedia

Zone melting (or zone refining or floating zone process or travelling melting zone) is a group of similar methods of purifying crystals, in which a narrow region of a crystal is melted, and this molten zone is moved along the crystal.The molten region melts impure solid at its forward edge and leaves a wake of purer material solidified behind it as it moves through the ingot.
