Technogenic waste from tin mining and processing can serve as a raw material source for the production of rare metals. In the present article, the content and distribution of Sc in cassiterite and tin tailings from the Khrustalnensky mining and processing plant (KMPP, Kavalerovsky district of Primorsky Krai) are considered, using the method of instrumental neutron activation analysis (INAA). An increased content of Sc in the sample of tails from the 3rd KMPP's tailings dump was shown. Determination of low concentrations of the element is possible using the INAA with a radionuclide neutron source based on Cf-252. The threshold for determining Sc was 1.6 g/t. The INAA analytical method used in the work also made it possible to determine the contents of La, Eu, Sm and In in the samples. [ABSTRACT FROM AUTHOR]
