Assaying Ores to determine gold content

The famous fire assay has been around for more than 500 years, but it still is the best method for determining the quantity of gold in a rock matrix. The fire assay process works by fusing or dissolving the rock sample in a crucible using a lead glass flux. Fluxes of various types are used on various types of ores.
