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.
Inquartation and Parting Refining Process
Inquartation and Parting. The technique mirrors part of the Fire Assay process used in the analysis (assay) of gold. Inquartation involves initially diluting the gold in the refinable material to about 25% (literally ''quartering'' the gold) by melting with the appropriate addition of copper or silver, granulating the melt so as to generate a high surface area and then treating with nitric acid.
