SCREEN FIRE ASSAYS AND GRAVIMETRIC FINISHES If a sample is identified to contain coarse gold a screen fire assay is the best way to obtain a definitive result. This procedure involves screening a large pulverised sample (commonly 1 kg) at 75 microns.

by M. A. McGuire

During the 16th century the basic fire assay procedure was essentially the same as that in use today. Although the use of the fire assay is now confined to the analysis of precious metals it was used in previous times for the assay of base metals such as lead bismuth tin and copper.

Chemistry Detailed directions are given for use of fire-assay techniques to separate and concentrate the noble metals Ag Au Ir Os Pd Pt Rh Ru from many varieties of samples. Included are procedures for selecting appropriate assay charges based on approximate chemical compositions of the samples.

Comparison of Silver and Gold Inquarting in the Fire Assay

The classical lead fire assay is still the most important method for the pre‐concentration and separation of Ag Au and some of the platinum‐group elements (PGE) in the analysis of geological materials. The most frequently used fire assay procedure is the determination of Au Pd and Pt with Ag as collector.

Chemistry Fire Assay

Fire Assay is a technique which analyzes the amount of precious metal (gold silver palladium and platinum) in a sample of ore or scrap. It is generally regarded as the most accurate (7-10 ppb or 0.1g/t) economical and consistent method for gold analysis though it is time consuming.
