Jan 26, 2013· The Gold Refining Forum Handbook Vol 1 has the Aqua Regia formula per Hoke as follows: "Hoke states 4 fluid ounces HCl + 1 fluid ounce HNO3 dissolves 1 troy ouncegold. This is equivalent to 31 mL HCl + 8 mL HNO3 per gram of gold."
It is eminently suited to the refining of low carat gold alloys, including white golds, and for those manufacturers and refiners dealing with relatively small quantities (a few kg per day) of largely 14 ct or lower materials, then it is likely that this technique will prove more economic than the aqua regia process.

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.
Gold parting is the separating of gold from silver.Gold and silver are often extracted from the same ores and are chemically similar and therefore hard to separate. Over the centuries special means of separation have been invented. The very earliest precious metals had mixes of gold and silver; gold and silver alloy is called electrum.With the advent of coinage, methods had to be invented to ...
