METHOD FOR EXTRACTION OF GOLD AND URANIUM FROM GOLD-URANIUM ORES Russian patent published in 2023 - IPC C22B60/02 C22B11/00 C22B3/06 

FIELD: hydrometallurgy.

SUBSTANCE: invention relates to the field of hydrometallurgy; it can be used for extraction of gold and uranium in leaching of collective gold-uranium ores and concentrates. Extraction of gold and uranium from gold-uranium ores includes combined leaching of gold and uranium from gold-uranium ores and concentrates with sulfuric acid and thiocyanate solutions in one stage. At the same time, leaching of gold and uranium is carried out at a temperature of 40-95°C, initial Eh of 450-550 mV, SCN^- ion concentration in the solution of 0.1-3 g/l, Fe³⁺ ion concentration in the solution of 1-5 g/l, and with sulfuric acid concentration in the solution of 5-50 g/l.

EFFECT: method allows for simplification of a technological scheme and reduction in costs for extraction of gold and uranium.
