    2017-4-24 · Gold is an almost non-reactive metal, but halogens — chlorine, bromine, fluorine and iodine — can dissolve it. Chlorine is the cheapest and lightest product that can achieve this. Bleach is the chemical compound sodium hypochlorite. When combined with hydrochloric acid, the mixture produces chlorine that dissolves gold from gold

  • Using Borax Flux to Refine Gold Manhattan Gold &

    2013-8-7 · 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.
