On the issue of studying diperse trace elements

Abstract

In the numerous ore and mineral formations of the deposits of our country, even such rare elements dispersed in the earth’s crust, such as thallium, germanium, cesium, cerium, indium, gallium, cadmium, hafnium, rhenium, etc., are undoubtedly concentrated. The listed elements usually do not form independent deposits, and their extraction is based on the fact that they are included in small quantities in the composition of some ores of ferrous and non-ferrous metals and other types of mineral raw materials. In creating a mobile raw material base for the elements under consideration, the primary task is a specific quantitative assessment of the values of certain contents in ores and large dumps of practically valuable components dipersed in all industrially interesting deposits, and primarily in deposits that will be put into operation in the coming years.
