Abstract

La présente invention concerne des ionites sélectives, et notamment, procédés de préparation de polyampholites par interaction de formaldéhyde et d'un sel d'acide hypophosphoreux avec des copolymères chlorométhylés de styrène aminés et réticulés. Les polyampholytes obtenus sont utilisables pour une extraction sélective des cations et des anions de métaux non ferreux et lourds, par exemple du tungstène, à partir de solutions technologiques et de pulpes, notamment en hydrométallurgie lors de la lixiviation au sulfate de concentré tungstène-molybdène, ainsi qu'à partir de solutions galvaniques et de l'eau de mer.
