Gold Assaying Methods Mineral Processing Metallurgy
To determine the amount of gold metal in ore there are two kinds of gold assay adopted . The dry assaying method ( by fusing the powdered ore with or without fluxes). The wet assaying method ( 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.
Submerge the metal in nitric acid. The acid will not dissolve the gold but it will dissolve the silver. You can then pour the solution through a filter to separate the gold. 7 9. Wash the gold. Wash the gold with water to remove any excess nitric acid. Pat the gold dry with a soft towel.
