what are the rules for processing gold with mercury

Gold panning - Wikipedia

Gold pans of various designs have been developed over the years, the common features being a means for trapping the heavy materials during agitation, or for easily removing them at the end of the process. Some are intended for use with mercury, include screens, sharp corners for breaking ice, are non-round, or are even designed for use "with or without water".

How to Refine Gold: 2 Major Techniques of Gold Refining ...

Mostly, the gold obtained through gold electrolysis is usually very pure, almost 99.999%. In fact, this procedure is the best method for processing gold with the highest karatage (24 Karats = 100 percent gold). This is why gold electrolysis is very common in countries where pure gold pieces are given priority over the ones with low karatage.

Summary of Mercury Amalgamation Gold Extraction Process

04-01-2020· The principle of gold extraction by using mercury (amalgamation method) is mainly that after the mercury is added to the slurry, the surface of the gold particles is wetted by mercury, and then the mercury diffuses into the interior of the gold particles, causing a chemical reaction. Au+2Hg=AuHg2. Finally, the solid of Au3 Hg will form.
