Extraction and processing of uranium ore in the USSR

The structure of X-ray photoelectron spectra of light actinide compounds

“…66 Knowledge of the uranium oxidation state in ores is especially important for underground leaching. 207,208 In a number of studies, 47, 65, 66, 92 ± 94 uranium compounds have been studied by XPS in order to develop a non-destructive method for determining the uranium oxidation states in compounds and minerals and the stoichiometric compositions of minerals on the basis of XPS fine structure parameters.…”

“…Determination of the relative contents of uranium ions in different oxidation states and the structural and phase compositions of natural uranium oxides (pichblendes) is very important for studying the conditions of formation of uranium deposits and for the exploration and development of the deposits. 208 Therefore, the possibility of using XPS studies for solving these problems has been evaluated. 65,66 The oxygen coefficients of the natural UO x oxides were determined according to the standard procedure; 6 the specimens of minerals were taken from the collection of the researchers.…”
