Apparatus and method of separating and concentrating organic and/or non-organic material
First Claim
1. An apparatus for segregating particulate material by density and/or size to concentrate a contaminant for separation from the particulate material feed stream, comprising:
- (a) a fluidizing bed having a receiving inlet for receiving the particulate material feed, an inlet opening for receiving a fluidizing stream, a discharge outlet for discharging a fluidized particulate material product stream, and a discharge outlet for discharging a non-fluidized particulate material stream;
(b) a source of fluidizing stream operatively connected to the inlet opening for introducing the fluidizing stream into the fluidizing bed to achieve separation of the fluidized particulate material product stream from the non-fluidized particulate material stream;
(c) reception means for receiving the fluidized particulate material product stream discharged from the fluidized bed; and
(d) a conveyor means for transporting the non-fluidized particulate material inside the fluidized bed through the discharge outlet to a reception means;
(e) wherein the fluidized particulate material product stream contains a reduction in the contaminant relative to the particulate material feed of about 23-54%, and the non-fluidized particulate material stream contains about 9-45% of the contaminant contained in the particulate material feed.

Abstract
An apparatus for segregating particulate by density and/or size including a fluidizing bed having a particulate receiving inlet for receiving particulate to be fluidized. The fluidized bed also includes an opening for receiving a first fluidizing stream, an exit for fluidized particulate and at least one exit for non-fluidized particulate. A conveyor is operatively disposed in the fluidized bed for conveying the non-fluidized particulate to the non-fluidized particulate exit. A collector box is in operative communication with the fluidized bed to receive the non-fluidized particulate. There is a means for directing a second fluidizing stream through the non-fluidized particulate as while it is in the collector box to separate fluidizable particulate therefrom.
