Based on the same basic principles as REFINEIT, this system condenses the gold refining process into a single, simple step and also makes the process clean, safe, and devoid of toxic fumes and even with possibility to work without acids and toxic waste! That's the breakthrough of the "Safe Gold Refining.
I would like to have experts' suggestion about an application of SX in small scale copper elector-refinery (3-5 Kt/Y) and if it is tangible, are there any successful references. Main concept is to refine 97-98% grade copper Anodes to 99.999 pure Cathodes by using SX circuit to control impuriti

If pure gold is required, additional refining steps are necessary to separate out the gold. While this procedure can be used on the very small scale (roughly up to 10 grams) such as in fire assay, its use on a small to medium scale (roughly 100 grams to 10 kg) is not recommended because it emits copious quantities of toxic lead oxide fumes.
The principle and equipment for gold electrolysis. Gold electrolysis was invented by Emil Wholwill in 1874. But various versions of this process have been developed over the years. It is an electrochemical process which has been applied in many large-scale gold-refining establishments or industries.
A wide variety of small gold refining machine options are available to you, There are 378 small gold refining machine suppliers, mainly located in Asia. The top supplying countries or regions are China, Vietnam, which supply 99%, 1% of small gold refining machine respectively.
Because it is time consuming-typically 24 hours or more-and suffers from the lock-up of gold inventory in the electrodes and electrolyte, the Wohlwill process is not suitable for small-scale refining. Fizzer Cell Process A variant of the Wohlwill electrolytic process, the Fizzer cell process is suitable for jewelers' small-scale refining ...
Typically, the input material for the anode is the gold from the Miller process, described previously. Because it is time consuming-typically 24 hours or more-and suffers from the lock-up of gold inventory in the electrodes and electrolyte, the Wohlwill process is not suitable for small-scale refining.
The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold.

An overview on how to refine precious metals. There are many kinds of materials that yield pure gold, platinum, or silver when refined. Though it's usually a little intimidating the first time you do anything, refining precious metals yourself is relatively easy to do (even with no experience) provided you have the right information, supplies, and equipment.
