摘要：<p>Process for the treatment of a hydrometallurgic suspension resulting from the etching of an ore containing at least one metal element to be valued, and acid-proof mineral materials of which a fraction is comprised of clays, consisting in removing the metal element to be valued, soluted during etching, by means of an organic solvent pertaining to the group of alkylphosphate characterized by insertion of a condensed mineral phosphate in the etching medium of the ore, in order to limit the losses due to adsorption of the removal organic solvent by the clays. The process applies more particularly to uranium-, molybdenum-, vanadium- and cobalt-bearing ores.</p>
