Gold Assaying Methods Mineral Processing Metallurgy

Sep 26, 2016 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 metals are thrown down.
