Document Type and Number:
Japanese Patent JPS5930651
Kind Code:
B2
Abstract:
Method for recovering uranium from a calcium fluoride aqueous slurry which contains less than 100 parts per million of iron. The slurry is passed through a high gradient magnetic separator which results in the detention of the uranium on the intermediate in the separator. The uranium is then removed from the intermediate by, for example, dissolution in a carbonate solution or a nitric acid solution. Uranium in the carbonate solution can then be removed with an ion exchange column and later removed from the ion exchange column with a nitric acid solution. Uranium in the nitric acid solution can be extracted using a DEPA-TOPO extractant.
