Short routine direct method for the fluorimetric determination of uranium in phosphate rocks

A short routine direct fluorimetric procedure for the determination of up to 0.06 percent uranium in phosphate ricks is described. The procedure employs a simple acid leach for preparing the solution, and the uranium is determined directly on a 1.8-mg aliquot. The results obtained by using this simply procedure on several thousand samples are discussed. The quenching of the uranium fluorescence by

Spectrographic analysis of coal and coal ash

Coal can be analyzed on the spectrograph for per cent ash and composition of ash in a matter of a few minutes, using the total energy method. The composition of the ash so determined can be used to calculate ash softening temperatures. This analysis can be made in sufficiently short a time to control tipple and washing operations for preparation of coal to meet specifications. This spectrographic
