THE SPECTROGRAPHIC DETERMINATION OF RARE EARTHS IN IRON FLUX CONCENTRATES USING A JARRELL-ASH 21-foot GRATING SPECTROGRAPH
Technical Report
·
OSTI ID:4229496
The concentrate from the chemical separation of the rare earths is spectrographed using a Jarrell-Ash grating spectrograph. The densities of the spectrum lines due to the rare earths are compared with those of iron added as internal standard and the concentration values obtained from a table of line-pair equalities.
