21. A separator system for separating copper from shredded waste, comprising:
a macro separator configured to perform an initial segregation of lighter material from heavier material in a stream of shredded waste; at least two copper recovery conveyors disposed below the macro separator, each copper recovery conveyor including a recovery conveyor belt inclined at an upward angle of between 0-15°, wherein the recovery conveyor belt is rotated by a motor so that a top surface moves upward along the upward angle, the recovery conveyor belt being formed of an elastomeric material having a planar base and a series of distributed wedge-shaped cleats projecting upward therefrom that carry heavier material including copper over an upper end of the recovery conveyor belt, the elastomeric material being 2-ply PVC with a durometer of 50 as measured on the A-scale, and a source of water at an upper end of the recovery conveyor belt to cause a constant flow of water downward over the top of the recovery conveyor belt so as to wash lighter material over a lower end of the recovery conveyor belt. |
