METHOD FOR LEACHING OF URANUS FROM ORE

摘要

1. A method of leaching uranium ores for heap or predominantly ISL comprising pre-cooking the leaching solution with its doukrepleniem sulfuric acid and an oxidant inlet artificial, filtering the leach solution through the ore with a transition therein oxidized ore minerals in the form of uranium ions and bivalent and trivalent iron , transfer them to the filtrate, extraction of uranium from the latter and receiving the mother liquor, characterized in that, after the preliminary preparation vysch -paying solution was further treated with an oxygen agent and adjusting the redox potential of the leaching solution by maintaining the ratio of concentrations of ferric ions and bivalent iron was less than 0.5, wherein the oxygen containing agent is introduced directly into stored pressure in the delivery line skvazhinu.2. A method according to claim 1, characterized in that the oxygen-containing agent used is air and / or oxygen-enriched air and / or technical kislorod.3. A method according to claim 1, characterized in that the mother solution is used repeatedly for the preparation of circulating leach solution.
