Abstract
A system and process for continuously separating and recovering materials from a heterogeneous mixture of particulate solids, from a solid waste or waste stream source, which uses a plurality of liquid media of different specific gravity to effect the separations, the solids having a plurality of different specific gravities and the recovered fractions each having a different specific gravity, wherein a first separation vessel receives the heterogeneous mixture, contacts the material with a first liquid medium having a first specific gravity of about 1.0, thereby causing a first part of the mixture to rise in the liquid medium as float particles, the remaining part to settle as sink particles, removing the separated float particles and sink particles without intermixture, then providing a second separation vessel, which receives the sink part from the first separation vessel contacts the material with a second liquid medium having a second specific gravity different from that of the first liquid medium, thereby causing a first particle of the material to rise in the liquid medium as float particles, the remaining part to settle as sink particles, and removing the separated float particles as a substantially organic particulate mixture, and the separated sink particles as a substantially inorganic particulate mixture, without intermixture between the product streams.
