Beschreibung
Zusammenfassung:	FIELD: hydrometallurgy. SUBSTANCE: method involves crushing ore, grinding and leaching valuable components with mineral acid and the following sorption extraction of dissolved uranium, molybdenum and vanadium from pulp. Before leaching a ground ore as an aqueous pulp is oxidized by treatment with anionite in OH-form at pH = 8.5-11.6, redox potential 50-150 mV and temperature 30-80 C. Leaching and sorption extraction are carried out by addition sulfuric acid to pH = 1.5-3.5 to oxidized pulp and anionite in sulfate form or anionite saturated at oxidation stage. Method provides reducing consumption of sulfuric acid and to improve ecology environment. EFFECT: improved extraction method. 4 tbl, 3 ex
