Assay Tests for Gold Mine Loans

Destructive, yet extremely accurate, fire assay testing is the standard for gold mining companies and major refineries. A significant reason why these major producers use fire assay methods is because they can further increase metals' accuracies, which can yield low ore concentrations levels that are 1g/T.

How to assay and evaluate placer gold deposits

Suppose the ore yielded by the assay just described, fine gold weighing .072 gram, it must be quite evident that a ton of the ore would yield the same decimal of one pound. Now one pound of gold is worth $301.46, and it is only necessary to multiply this value by the weight of gold obtained in grams and decimals to find the value of the gold in
