How can you get the Pure gold from aqua regia and gold solution?

Answer 1

Several ways to do that. One way is adding hydrochloric acid and vaporizing

to initial volume. That action causes nitric acid (from the aqua regia) to go out.

Repeat this action 3 times. Now add copperas - ferrous sulphate dissolved in

hydrochloric acid 15%. The gold will precipitate. You can wash it if necessary

1stly in hot hydrochloric acid, 2ndly water, 3rdly ammoniak, 4thly water.

The resulting gold should be at least 99%

Answer 2

Pure gold can be obtained from aqua regia and gold solution by adding a reducing agent, such as sodium metabisulfite, to the solution. The reducing agent will cause the gold to precipitate out of the solution in the form of a fine powder or solid. The solid gold can then be collected through filtration and further purified if necessary.
