  • How to refine gold

    The second method of refining gold involves the use of chemicals. Strong acids are used to dissolve the impurities in the gold ore and afterwards are neutralized and washed away taking the impurities with them. The resulting product is a muddy substance that is almost pure gold (99.999 or 24K).
