A process for purifying and refining gold to 98+% purity is dislosed. The gold to be refined is made the anode in an electrolytic cell with a solution of ammonium chloride as the electrolyte. The purified gold is collected in anode bags and the non-gold impurities including silver are dissolved in the electrolyte. The silver is complexed with the ammonium ion in the electrolyte.

The Wohlwill process is necessary for highest purity gold applications, and when lower purity gold is required refiners often utilize the Miller process due to its relative ease, quicker turnaround times, and because it does not require a large inventory of gold, in this case gold chloride, on site at all times.. A variant of the Wohlwill process is the fizzer cell.

Gold Refining. The gold refining process is about extracting as well as separating precious metals in doré from electronics and jewelry (recycled products). Many techniques contribute to pulling out the final impurities so that high caratage gold can be obtained. The key techniques used in this regard include Cupellation, Fizzer Cell, Miller Process, Wohlwill Electrolytic Process ...

The final stage of gold production -- refining-- involves removing impurities that remain after the smelting process.Refining companies receive doré bars, as well as scrap gold, and reliquefy the metal in a furnace. Workers add borax and soda ash to the molten metal, which separates the pure gold from other precious and less precious metals. A sample is then taken to a lab for tests, or ...

Gold refining techniques include the aqua regis process, fizzer cell, Wohlwill process, Miller process, cupellation and more. The most popular method used is the Miller method, but it's not the most popular method for ABC Refinery ATO. The Miller process may be the easiest to utilize but it produces gold around a 99.5 percent purity.

I am looking at refining some alluvial gold. So not a lot of junk to filter out. Electro chemistry seems ideal given the lack of toxic gasses but does require some specialised equipment such as a semi permeable membrane (usually ceramic) for a fizzer cell. I take your point regarding people packaging up common chemicals and charging a fortune.

The gold anodes are made exclusively from the gold from the silver-cells, which assays about 875 thouhs gold, from 100 to 125 thouhs silver, and a small amount of base metals. This gives, in the first cells, cathodes about 998.7 fine, which, on being re-treated in the second set of cells, produce gold about 999.7 fine.

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.
