METHOD OF URANIUM EXTRACTION FROM DILUTED SOLUTIONS AND NATURAL WATERS Russian patent published in 2017 - IPC C22B60/02 C02F1/28

Abstract RU 2625150 C1

FIELD: chemistry.

SUBSTANCE: uranium is extracted from the solution by sorption on a chemically activated shungite modified with zinc hydroxide at a mass ratio of shungite: zinc hydroxide of 7:1. As a result of the test, a 6.35% uranium concentrate was obtained. The rate of extraction of uranium in this case was 86%.

EFFECT: invention makes it possible to increase the uranium recovery rate and to obtain an uranium concentrate with a higher content of uranium.
