Nov 03, 2016 Assuming ideal conditions and a perfect core, the value of the hole (or the sample increment) would be determined by use of the following equation: cents per cubic yard = W x V x 27/A x D. in which W = weight of gold in milligrams. V = value of gold in cents per milligram. A = effective area of drive shoe in sq. ft.

Aug 08, 2021 The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it ...
