How can you extract gold from an alloy using nitric acid?

Answer 1

Can't do. Nitric acid would vaporize if added to molten gold.

Answer 2

To extract gold from an alloy using nitric acid, you can dissolve the alloy in nitric acid, which will selectively dissolve the base metals in the alloy, leaving behind the gold. Once the base metals are dissolved, you can precipitate the gold from the solution by adding a reducing agent, such as copper or ferrous sulfate, which will cause the gold to drop out of the solution as a solid. Finally, the solid gold can be filtered out and further refined to obtain pure gold.

Answer 3

Nitric acid will not dissolve gold, but it will dissolve most other metals; you could use it to dissolve the non-gold portion of the alloy, leaving the gold behind.
