Zinc powder is then added to solidify the dissolved gold. To smelt into bars a chemical cocktail is prepared – manganese dioxide, fluoride, silica flour, borax and sodium nitrate. This mix – called flux – separates the gold from the impurities. Smelting occurs at 1600 degrees centigrade. The smelter is rotated so that the contents heat evenly.
