<h3>Gold Refining Methods, Wohlwill process, Miller processes </h3><p>Before a process can be chosen, the gold meant for refinement has to be evaluated for gold content. Once the amount of gold contained has been established, refining can begin. The Wohlwill and Miller processes are the two main methods used to refine gold today. The Wohlwill process creates gold to a high level of purity (99.999 percent). </p>
