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. 1. Aqua Regia Refining The principle and equipment for Aqua Regia. Aqua Regia has been used to separate gold
The gold refining technique described here is the rather ancient wet chemical method whereby the gold-bearing scrap is dissolved in aqua-regia. m is gold solution is then filtered and the jewelers bench dirt, sandpaper grit, grinding wheel grains and similar material remains on the filter as a solid sludge, together with any silver present which will be in the form of silver chloride.
K-JHIL – gold refining systems are ideal for old gold jewellery buyers, bullion suppliers, gold smithies, jewellery casting and chain manufacturing factories, job-work refineries etc., as they come in various capacities, to suit small or larger refining needs of the jewellery trade. K-JHIL – series of gold refining systems are among the most advanced in-house refining systems
The procedure is very similar to refining gold in aqua regia, but the precipitant used will be different. There are several standard precipitants, different precipitants for different platinum group metals. Refining by this method is tricky and the purity of the resultant platinum group metal is often below normal standards. Refining of platinum metals is best done by the saltwater method.

Aqua regia is a 3:1 mixture of hydrochloric acid and nitric acid. It is a strong oxidizing mixture that dissolves many base metal sulfide minerals as well as gold and platinum. However, it is a partial leach that leaves an undigested silicate and alumina residue as well as refractory minerals such as garnet and spinel. It is possible to vary the sample size from less than 1g up to 20 to 50g ...
The aqua regia is formed by mixing 425 ml of concentrated hydrochloric acid and 150 ml of concentrated nitric acid. The resulting mixture is stirred and heated to about 40°C. The gold completely dissolves in the aqua regia to form a clear, golden-colored solution. The solution is cooled to room temperature.
