Using Borax Flux to Refine GoldManhattan Gold Silver

 · 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.
