Aqua Regia Process. The Aqua Regia process can produce gold of up to 99.99 percent purity. It is based on the fact that Aqua Regia (a mixture of hydrochloric and nitric acids in a 4.5:1 ratio) can dissolve gold into soluble gold chloride. The process is most suited to medium- to large-scale operations.
