• Solvent Extraction - an overview | ScienceDirect Topics

    Direct solvent extraction: This process involves the use of a nonpolar solvent, usually hexane, to dissolve the oil without removing proteins and other non-oil soluble compounds. Solvent extraction yields about 11.5% more oil than does the screw press method, and less oil remains in the meal.

  • Solvent extraction of copper by hydroxy oximes - ScienceDirect

    The solvent extraction equilibrium and kinetics of copper extraction by a proprietary β 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.
