    摘要： Uranium ore deposits which contain uranium in the relatively insoluble tetravalent state are readily selectively leached in situ to recover relatively pure uranium compounds, by: (a) passing through the ore deposit a relatively dilute aqueous leach solution of ammonium bicarbonate, ferric ammonium ethylenediaminetetraacetic acid (EDTA), and a source of oxygen, the leach solution converting the tetravalent uranium to hexavalent uranium which readily dissolves in the leach solution; (b) withdrawing the reacted leach solution enriched in dissolved uranium from the ore deposit; and (c) stripping the uranium from the withdrawn leach solution. The stripping of the uranium from the leach solution is preferably accomplished by countercurrent flow of the enriched leach solution to a column of base anion exchange material which preferentially extracts the uranium. Base anion exchange material loaded with uranium is separated from the leach solution and is treated with an aqueous alkaline eluant to extract the uranium and to regenerate the base anion exchange material. The stripped leach solution is adjusted by adding ammonium bicarbonate, peroxide, and ferric ammonium EDTA, and its pH corrected if necessary, and the leach solution is recycled through the ore deposit. The uranium bearing eluant is then acidified and treated with ammonia to precipitate relatively pure ammonium diuranate (ADU).

    摘要： The oxidation of uranium is catalyzed with water-soluble copper or zinc chelates. An aqueous solution is prepared containing carbonate or bicarbonate ion, an oxidizer such as hydrogen peroxide or oxygen, and a water-soluble copper or zinc chelate which has at least two amino, carboxylic acid, or thiocarboxylic acid donor groups. The solution is pumped into an underground deposit of uranium. The water-soluble +4 state uranium is oxidized to the water-soluble +6 state which forms a complex with the carbonate ion. The solution is pumped to the surface and is recycled after precipitation of the uranium.
