Gold Assaying Methods 911 Metallurgist

2016-9-26  If the ore is assayed for ordinary metals, such as lead, then weight of resulting metal/weight of sample of ore x 100 = percentage of metal in the ore. For weighing gold, silver, or platinum, the troy weight is sometimes used ; for weighing other metals, avoirdupois. The decimal system of grammes and decimals of a gramme is convenient for both.
