Various ore fractions (and mixtures thereof), of which the main metallic components are iron, copper and zinc, were analysed by means of radioisotope X‐ray fluorescence spectroscopy using a Si(Li) detector. As a result existing equations which deal with interelement effects (selective attenuation and enhancement of characteristic radiation) were further developed, and a new set of general equations, which accounts for the important interelemental background contribution, has been formulated. Its validity has been experimentally tested over a wide range of concentrations which, in some cases, varied by as much as a factor of 200. Satisfactory results were obtained.
