  • Using Borax Flux to Refine Gold Manhattan Gold & Silver

    07.08.2013· With some borax, heat, and a little know-how, it’s possible to extract pure gold from a sample of ore. This is because using borax as the flux reduces the melting point of all the elements in a piece of ore, including gold. While out in the field, a gold prospector can grind and wash a piece of ore, then mix it with borax in a plastic bag. The bag is then placed in a bowl or crucible and heated. The heating action is what triggers the borax to go to work. Once the borax
