Gold Assaying Methods
To determine the amount of gold metal in ore, there are two kinds of gold assay adopted:. The dry assaying method (i.e. by fusing the powdered ore with or without fluxes).; The wet assaying method (i.e. by the agency of liquids).; In the principal wet assay, the ore is thoroughly dissolved in acids, and, by the addition of reagents, precipitates containing the …
