Analytical Method for THE SPECTROGRAPHIC ANALYSIS (GENERAL METALS) OF URANIUM ORES AND CONCENTRATES BY THE CARRIER-DISTILLATION METHOD

摘要

The ore or concentrate after ignition is diluted with spectrographically pure"U308,” and mixed with 5% by weight of silver chloride carrier. The mixture is placed in a graphite cup which is made the anode for excitation in a d.c. arc at 10 — 12 amp. Spectra are recorded photographically using a large quartz spectrograph.
