How is gold refined into high-purity bullion? | Provident
Gold panning is a simple and rudimentary form of this process. Physical sifting and separation, at best, are just initial steps. To attain a high level of purity, there are only two options: using heat or chemicals. Melting ore results in the actual fine gold settling to the bottom of the liquid mix while the impurities rise to the surface.
