Assaying Gold and Silver Ores: Fire Assaying and Other

2014-6-26  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.

2011-5-19  Since then I have purchased some more literature on fire assaying (a textbook of Fire Assaying By Edward E. Bugabee, and Fire assaying by Shepard & Dietrich). The main ore I'm working with at this time is an altered basalt with quartz fissures, and misc sulfides. As a whole there is very little quartz, compared to the average gold in quartz ore.
