Epithermal neutron activation analysis using an internal single comparator has been used for the analysis of Saudi Arabian iron ores. The concentration of thorium, barium, terbium, tantalum, cobalt, lanthanum and antimony was determined using iron in the ore as an internal comparator for all the elements. In case of antimony there was an agreement between this method and the conventional method indicating that the given method is accurate.
