Alternative equilibrium modifiers for use with aldoxime extractants, such as hydroxyl aryl aldoxime extractants, employed in the process for extraction of metal values, particularly copper values, in the extraction from aqueous solutions, in which the extractant and modifiers are employed in an organic solvent phase, the solvent being a water insoluble, water immiscible hydrocarbon solvent, such as a kerosene.
On emploie des modificateurs d'équilibre différents, avec des solvants d'extraction aldoxime, tels que l'hydroxyle aryle aldoxime, dans le procédé d'extraction de métaux précieux, notamment du cuivre, dans l'extraction à partir de solutions aqueuses, le solvant d'extraction et les modificateurs étant utilisés dans une phase de solvant organique, lequel est un solvant d'hydrocarbure, non miscible avec l'eau et non soluble dans celle-ci, tel qu'un kérosène.
