Fire assaying is defined as a branch of quantitative chemical ana1ysis, which is applied in determining the precious metal, content of ores, metallurgical products, and scrap material. The method is a pyro-metallurgical technique which separates the metal to be determined from the impurities and gangue present in the sample. A metallurgical assay is a compositional analysis of an ore, metal, or alloy.. Some assay methods are suitable for raw materials; others are more appropriate for finished goods. Raw precious metals are assayed by an assay is assayed by titration, gold by cupellation and platinum by inductively coupled plasma optical emission spectrometry (ICP OES).

The noble metals present the ultimate challenge to the analytical chemistry researcher. Difficulties are encountered in every analytical step from first comprehensive treatment of the subject of Au and Ag assaying was by Lazarus Ercker in his book, Treatise on Ores and Assaying ub1ished in While noble metals retain their shiny color, base metals tend to oxidize in moist air.
However, some metals that resist corrosion are not considered noble metals. These include titanium, niobium, and tantalum. In atomic physics, the noble metal group consists of copper, silver, and gold. Book VII: On the assaying of ore. This book deals with assaying techniques.
