    Nov 16, 2020 Gold concentrate is combined with a flux, such as borax or other materials of mixtures, in the crucible. The flux acts to decrease the melting temperature and viscosity of non-gold minerals in the concentrate so they are more easily separated from the gold during the cooling process. Small amounts of concentrates, usually around 50 to 100 grams, are used in direct smelting. Concentrate and flux are heated in the crucible to the temperature at which gold
