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 …

An idea of the amount of this could be arrived at by weighing the ore as it is trucked out and checking by the amount of waste going over the dump, if the ore is one which lends itself to sorting. The old controversy as to trial crushings versus sampling, plus assay, plus judgment, has, it is considered, been fully answered by leading authorities.
