    Download a copy of Geological Survey Bulletin , " A Manual on Fire Assaying and Determination of the Noble Metals in Geological Materials". Here's what the intro says: 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. 2 A complete listing of assay and analysis methods, with a description of how they work, is beyond the scope of this report. A good place to start when researching assay methods is U.S. Geological Survey Bulletin (), A Manual on Fire Assaying and Determination of the Noble Metals in Geological Materials.

    Optimisation of fire assay conditions for gold determination Fire assay parameters studied These parameters are well known and are discussed in a lot of various papers and books. From our experience, we have retained the following 20 parameters: 1. Balance 2. Assay weight 3. Composition of the assay (Au, Ag, Pt, Pd, Cu, common metals) 4.

    The beginning history of fire assaying can be traced to the finds in Troy II (about B.C.) and in the Cappadocian Tablets ( B.C.). These finds prove that very pure silver was made in the twenty-fifth century B.C. From this evidence we must conclude that the cupellation process, and therefore fire assaying, was invented in Asia Minor in the first half of the third millennium B.C.

Particular emphasis is placed on the fire assay, the technique most favored by noble metal analytical chemists both past and present. Fire assaying is an ancient form of quantitative chemical analysis by which metals are separated and determined in ores and metallurgi­ cal products with the aid of heat and dry reagents.

In the last decade, bismuth trioxide has also become a key ingredient in flux formulations used by mineral analysts in fire assaying.

The production of bismuth trioxide generally begins with the minor metal bismuth. This paper describes bismuth trioxide production and the properties and basis for its use in environmentally sound fire by: 6.

Dana),   Methods for the determination of noble elements in geological materials have been described in detail by Haffty and others. 2 As dross is refractory and chemically inert, an elaborate and time‐consuming procedure is required for bringing it into solution.

Also, during decomposition, there is risk of contamination, directly or through reagents. The method used to measure the amount of metal (or other commodity) of interest is called assaying.

The most common and reliable method for assaying rock for silver, gold or other precious metals (platinum group elements) is fire assaying. This method was used in. Sample Digestion Methods for the Determination of Traces of Precious Metals by Spectrometric Techniques.
