How To Refine Gold 2 Major Techniques Of Gold Refining

Two (2) major techniques for refining gold. Generally, gold can be refined using these two-best-known gold-refining procedures: Aqua Regia and gold electrolysis. Both of these techniques can be used to separate gold from other metals. This is because a little piece of other metals in gold can change its properties and value.
