Aqua Regia Process. The Aqua Regia process can produce gold of up to percent purity. It is based on the fact that Aqua Regia (a mixture of hydrochloric and nitric acids in a :1 ratio) can dissolve gold into soluble gold chloride. The process is most suited to medium .
Gold and most other metals will dissolve in aqua regia; silver, however, will form a silver chloride precipitate. Because of this reaction of silver, it is necessary to restrict the amount of silver in the start material to be refined to a maximum of 10%; any more than this will run the risk of the silver chloride preventing complete dissolution of the gold by masking it off.

Then by dissolving ammonium chloride into this acid, he prepared aqua regia which, unlike acids, could dissolve gold in it. Jabir classified chemical substances, on the basis of some distinctive features, into bodies (gold, silver, etc.) and souls (mercury, sulphur, etc.) to make the study of their properties easier.
