    The solvent extraction equilibrium and kinetics of copper extraction by a proprietary hydroxybenzophenone oxime, LIX65N, have been studied using an AKUFVE. Addition of an aliphatic hydroxy oxime, LIX63, to the LIX65N has been shown to enhance the rate of extraction of copper without affecting the equilibrium distribution.
