For Reference Only At Bureau Libraries :18 pages
This report reviews the practices of analyzing for precious metals at the Reno Research Center, U.S. Bureau of Mines. A general description of fire assaying, the physical layout of a fire assay laboratory, and the use of fire assaying in combination with atomic absorption, induction coupled plasma, and emission spectroscopy is reviewed. The combination of techniques significantly decreases the detection limits for precious metal analyses and simplifies the analysis of the platinum-group metals. Methods of protecting personnel from ingestion of lead are also discussed.
