Dissolving Gold and Precipitating Gold - Pyrometallurgy ...

If you want to leach gold you need an oxidizing environment (add chlorine gas or clorox) until you reach an ORP of 1000mV, at a Ph of about 5, hopefully warm temperature and you will leach gold. Once in solution, separate liquid from solids, reduce the ORP to 100 -500 mV using NaHSO3 and your gold will precipitate.
