Title (EN) REDUCTION OF ORGANIC SOLVENT LOSSES IN HYDROMETALLURGY
(FR) REDUCTION DES PERTES EN SOLVANT ORGANIQUE EN HYDROMETALLURGIE
Abstract: front page image
(EN)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.
(FR)Procede de traitement d"une suspension hydrometallurgique resultant de l"attaque acide d"un minerai contenant au moins un element metallique a valoriser, et des matieres minerales inattaquables dont une fraction est formee d"argiles, consistant a extraire l"element metallique a valoriser, passe en solution lors de l"attaque, au moyen d"un solvant organique appartenant au groupe des alkylphosphates qui se caracterise par l"introduction d"un phosphate mineral condense dans le milieu d"attaque du minerai, dans le but de limiter les pertes par adsorption du solvant organique d"extraction par les argiles. Le procede s"applique plus particulierement aux minerais uraniferes, molybdeniferes, vanadiferes et cobaltiferes.
