In a search for internal isotopic tracers in metallurgical materials a group of elements has been chosen which can be determined
by the neutron activation method with the higher sensitivity. A method has been developed for the determination of W, As,
Au, La, In, Sc, Re and Ir in metallurgical materials. The separation of the elements was carried out using extraction and
precipitation. The determination of the elements was carried out in samples of chamotte brick and washed ores. The limits
of the determination of the elements are of the order of 10−11 g for Au, 10−10 g for In and La and 10−9 g for As, W, Sc, Re and Ir. The large scatter of the results indicates the inhomogeneity of the materials analyzed.
