Abstract
An ore containing an increased percentage of mineral values, particularly uranium values, is separated from an ore containing a lower percentage of such mineral values by contacting the ore containing the lower percentage of mineral values with a polar solvent, particularly water, and a nonpolar solvent, such as an isoparaffin mixture, and separating a polar solvent phase containing a portion of the contacted ore from a nonpolar solvent containing another portion of the contacted ore. The ore may be a total ore containing both coarse and fines or a fines fraction which has been separated from a total ore as by wet classification. Where a total ore is treated in accordance with the present invention, in one embodiment of the invention, a coarse ore fraction can be separated from the total ore either during the contacting step or the separating step. A method of recovering mineral values from a ground ore is disclosed, which includes recovering such mineral values from an ore fraction which has been enriched in such mineral values as set forth above.
