Abstract
The federal Bureau of Mines has developed an accurate, sensitive, and reasonably rapid method for the determination of rhenium in ores, concentrates, and tailings. The sample is solubilized by a novel fusion procedure or by a simple digestion technique. Rhenium in the resulting solution is extracted with a commercial quaternary amine in methyl isobutyl ketone, and the organic phase is aspirated directly into a nitrous oxide-acetylene flame. An accuracy of about 1 percent is achieved, based on the analysis of an NBS standard sample. The detection limit for a 5-gram sample is about 1 part per million.
