Apr 28, 2007 My policy was to add about 105% in silver of the weight of the mixed scrap gold Id process. It kept me in the ballpark. Considering 14K is 58.3%, you ended up quite close to 25% gold content. The problem with inquarting too low (under 25% gold) is
Gold can be mixed with other metals like copper, which is used in red gold, or mercury, which is used in dental gold. Gold is a very pliable metal and its melting point is relatively low therefore, refining it by melting it and extracting the other metals from it is a practical process.
