An inert dilution method for the X-ray fluorescence analysis of niobate-tantalate mineral concentrates

Abstract

An X-ray fluorescence method, in which iron(III) oxide is used as inert diluent, is described for the determination of niobium, tantalum, tin and titanium in concentrates of polymineral composition. No time-consuming fusion procedures or tedious calculations are involved. The simplicity and rapidity of the method merit its use in routine analysis. Good agreement with chemical analysis is obtained.
