Using Borax Flux To Refine Gold Manhattan Gold Amp Silver
Aug 07, 2013 With some borax, heat, and a little know-how, its 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.
