ABSTRACT:
An improved extraction apparatus comprises (a) an elongated trough-like vessel; (b) first and second inlets for introducing relatively heavy and light materials, respectively, into the vessel; (c) first and second outlets for removing relatively light and heavy materials, respectively, from the vessel; (d) a plurality of horizontally spaced parallel plate assemblies located in the vessel to provide for material separation based on material density and to provide the relatively light and heavy materials to be removed from the vessel; and (e) a plurality of agitation devices, at least one device being located in each space between the parallel plate assemblies to facilitate contact between the materials present in the space.
Improved methods for extraction are also disclosed.
