TheMiller processuses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. TheMiller processis rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwillprocessincreases purity to about 99.99 percent by electrolysis
