SOLVENT EXTRACTION

摘要

Reagents formulated by admixture of selected hydroxy aryl ketoxime and hydroxy aryl aldoxime extractants provide for efficient recovery of metal values, especially copper values, by solvent extraction processes. Reagents may include from 0 to about 20 mole percent of a kinetic additive based on ketoxime content and also optionally a modifier of extraction and stripping equilibria in an amount providing a degree of modification of the aldoxime constituent of from about 0.66 to 1.0.
