Artisanal and Small Scale Gold Mining Without Mercury

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.
