Abstract

The invention is a novel method for the recovery of uranium from dry, particulate uranium tetrafluoride. In one aspect, the invention comprises reacting particulate uranium tetrafluoride and calcium oxide in the presence of gaseous oxygen to effect formation of the corresponding alkaline earth metal uranate and alkaline earth metal fluoride. The product uranate is highly soluble in various acidic solutions whereas the product fluoride is virtually insoluble therein. The product mixture of uranate and alkaline earth metal fluoride is contacted with a suitable acid to provide a uranium-containing solution, from which the uranium is recovered. The invention can achieve quantitative recovery of uranium in highly pure form.

Separation and recovery of molybdenum values from uranium process waste

Patent Nalewajek, D.; McCurry, L.E.; Friedland, D.J.; ...

A method is described of recovering molybdenum and uranium values from a process waste generated from the production of nuclear-grade uranium hexafluoride which consists of: (a) hydrolysing the process waste which contains UF/sub 6/, MoF/sub 6/ and MoOF/sub 4/ in an aqueous solution containing ammonium carbonate and ammonium hydroxide thereby forming ammonium uranyl carbonate; (b) digesting while maintaining a pH > 9, the resulting mother liquor at a temperature of about 60/sup 0/-80/sup 0/C. to evolve CO/sub 2/ and convert the ammonium uranyl carbonate to solid ammonium diuranate; (c) filtering, washing and drying the solid ammonium diuranate.
Recovery of fluorine, uranium, and rare earth metal values from phosphoric acid by-product brine raffinate

Patent Wamser, C.A.; Bruen, C.P.

A method for recovering substantially all of the fluorine and uranium values and at least 90 percent of the rare earth metal values from brine raffinate obtained as by-product in the production of phosphoric acid by the hydrochloric acid decomposition of tricalcium phosphate minerals is described. A basically reacting compound is added to the brine raffinate to effect a pH 9 or greater, whereby fluorine, uranium and rare earth metal values are simultaneously precipitated. These values may then be separately recovered from the precipitate by known processes.
Method for recovery of metal values from secondary copper-smelter flue dusts using an ammonium carbonate-ammonium hydroxide system

Patent Gabler, R.C.; Jones, J.R.

A process wherein the secondary copper smelter flue dust is leached at room temperature with a solution containing ammonium carbonate ((NH/sub 4/)/sub 2/CO/sub 3/) and ammonium hydroxide (NH/sub 4/OH). The pregnant leachate is filtered from the leach residue which is now enriched in tin. Typically, 65% of the flue dust dissolves, leaving only 35% for sale or disposal. The pregnant leach solution is heated to 60/sup 0/C to facilitate cementation of copper and lead from the leachate. After removing the copper-lead rich cementate by filtration, the filtrate is cooled to room temperature. Carbon dioxide is injected until pH 7 ismore »« less
