Gold Chlorination Processes & Methods
31-08-2016· Dry Chlorination Chlorination Process for Gold. This process was based on the fact that chlorine, in the presence of moisture, converts gold into the trichloride AuCl3 , which is soluble in water and removed by washing, the gold being then precipitated by ferrous sulphate, sulphur dioxide, hydrogen sulphide, or charcoal.
How does gold react with chlorine? | Gold Refining & Metal,
26-07-2008· Ah, very convenient for you that I have actually done the chlorination of Au, Pt, Pd, and others quite a bit! FYI, wet chlorine will attack pretty much every metal, Cu and Fe do not react with dry chlorine. I can tell you how to most efficiently make chlorine and dry it. Yes, it's a good way to purify gold and the PGMs, and good for separation.

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.
