    Radioisotope X-ray fluorescence analysis of powdered metallic ores has been carried out by means of a portable instrument. Description of and experience with this instrument are included. Elements investigated were Cr, Ni, Cu, Zn, Zr, Nb, Mo, La plus Ce, and Pb. Typical powdered ore minerals of these elements were mixed with powdered material of granitic or gabbroic composition, and calibration curves were established by plotting thedifference count rates obtained by means of the portable X-ray fluorescence analyser against the contents of the elements in the mixtures. Regression analysis of the lower linear part of these curves yielded detection limits and accuracies, both of the order of 0.1 %.
