THE DETERMINATION OF THORIUM IN THORITE ORES

Technical Report · Fri May 01 00:00:00 EDT 1959

OSTI ID:4254471

The ground sample is leached by refluxing with nitric acid. The resulting solution is filtered, and the soluble portions are treated separately. The soluble thorium is purified by passage through a cellulose -- alumina column precipitated first as hydroxide, then as oxalate, and finally weighed as the dioxide. The insoluble thorium is brought into solution by a fluoride--hydrogen sulfate fusion, purified by extraction with TBP --xylene, and finally determined absorptiometrically as its thorin complex. The method is applicable a Nigerian thorite with thorium concentration 5-- 10% Th. (auth)
