    Aqua regia process can be used to separate gold from othe metals also If we have gold mixed with other metals, we can separate it by using AR process on it To get 24K gold, finally we can use aqua regia process We can use AR to recover gold fromThese methods were considered as of low impact on the environment and effective, however, because release of gold from an extractant can be challenging, the attention of researchers turned to other areas There are examples of works describing optimization ofThe recovery of gold from the aqua regia leachate ofHow To Use Aqua Regia To Purify Gold Place your gold or finely powdered ore in a Pyrex container breaker Mix 1 part nitric acid to 3 parts hydrochloric acid in a separate glass or plastic container When mixing the acids together, use great caution! Add the acid mixture, very slowly, to the Pyrex container or beaker containing the oreHow To Use Aqua Regia To Purify Gold
