ABSTRACT:
A method of extracting components from particulate materials is disclosed. The method includes the steps of mixing the particles with a first extraction solvent to provide a slurry. The slurry is then passed through an extraction zone. A second extraction solvent is passed countercurrently to the slurry through the extraction zone. The second solvent has a different density from the first solvent and is substantially immiscible with the first solvent. This process is particularly beneficial for use in the extraction of ground oil-seed particles.
