    SX Solvent Extraction Process Principles Theory

    Description of the Solvent Extraction Process. Solvent extraction (SX) is applicable in any instance where it is desirable to selectively remove or extract a species from one solution into another. This can apply either to the removal of a valuable component from contaminants or to the removal of contaminants from the valuable component.
