With this plant it is possible to obtain gold with a purity of 999,9/1000 starting from 900/1000 with a maximum silver content of 5 %. Each 35 lt tank produces from 12 to 15 Kg each in 24 hours. the electrolyte solution should contain 80gr/lt of gold chloride. the plant consists of a single cell divided into two tanks, made out of selfextiguishing ppl, and resting on a safety tray. the ...
The acid mixture aqua regia, or royal water, dissolves gold and is used to purify scrap alloy containing gold. Aqua regia is a mix of three parts hydrochloric acid to one part nitric acid. The dissolved scrap gold forms gold chloride. The chlorides of silver and platinum may also be present.
The gold detection test is sensitive to around 4 parts of gold per million parts of solutionthe maximum loss of metal left dissolved in solution. Refining Platinum (Aqua Regia) When platinum group metals are mixed, it is very complicated and difficult to refine them using aqua regia.
23/09/2008 Scrap recovery using Aqua Regia 2003. Q. Scrap recovery using Aqua Regia. I also do scrap recover as a hobby and for learning the silver and gold work fair in this process but we have no luck in the recovery of platinum from catalytic convertor honey combs can anyone please comment on this.

Generally, gold can be refined using these twobestknown goldrefining 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. 1
Apr 11, 2012· I''m not trying Aqua Regia, at least not yet because I''m doing this at home. So I found a bunch of posts on different sites regarding Gold Transfer VIA Electrolysis, along with many videos. All pretty much state the same thing. Use the following 1. Use electrolysis to recover gold .
Other less common methods are cupellation, inquartation and parting, fizzer cell, aqua regia, and the pyrometallurgical process. According to the World Gold Council, the Miller process uses gaseous chlorine to extract impurities when gold is at its melting point. Impurities separate into a layer on the surface of the molten purified gold.

The reaction of gold and aqua regia produces toxic fumes so the process must be conducted outside or in the fume hood. It takes around 20 minutes for gold to dissolve at room temperature. At the end of the reaction, we have the solution of dissolved gold and copper compounds and solid crystals of silver salts.
