Q

It is considered the most reliable method for
accurately determining the content of gold, silver,
and platinum-group metals (except osmium and
ruthenium) in ores or concentrates. This process
involves melting a gold-bearing sample in a clay
crucible/cupel at >1000 °C with a mixture of fluxes
(such as silica and borax), lead oxide (called
litharge), and a reducing agent (frequently flour).

A

Fire Assay
