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.

Dec 08, 2009 You can send us samples of the raw ore and we can analyze them for $75-$150 depending on the size of the rock you send us. If we end up refining it we will not charge you the fee for testing. We can return to you a large percentage of gold value after refining but the exact amount will depend on the quality and volume you find.

Apr 24, 2017 Gold is an almost non-reactive metal, but halogens — chlorine, bromine, fluorine and iodine — can dissolve it. Chlorine is the cheapest and lightest product that can achieve this. Bleach is the chemical compound sodium hypochlorite. When combined with hydrochloric acid, the mixture produces chlorine that dissolves gold from gold ore.

The ancient process of refining gold has already been described under METALLURGY (which see). Most of the Bible references are to the refining of silver ( Proverbs 25:4 Zechariah 13:9 Isaiah 48:10 ).
