ABSTRACT:
A procedure and apparatus are shown for on a continuous, commercially practical basis recovering a non-ferrous base metal, such as copper or aluminum in the form of clean, bright metal pieces or bits and for enabling recovery of different non-ferrous coating metals, such as of lead, tin or alloys thereof, and under conditions in which a resin insulating coating may be present. Mechanical shredding means is used for reducing insulated wire to an aggregate containing bits, particles or pieces within a requisite size range, extraneous magnetics are removed, and the content of resin coating material is reduced under dry conditions to within a maximum of 2%. A preliminary step for attaining a less than 2% resin content importantly includes moving the aggregate as a vibration-activated, dry, fluid mass of substantially uniform thickness upwardly along a spiral path while separating the material into heavier and lighter portions, with the lighter innermost portion being recycled to further concentrate the metal bit content thereof and to further minimize the resin content thereof.
After the resin content has been thus reduced, and the metal bit content maximized, the aggregate is again moved along a fluidized helical path in a vibration-activated stream of substantially uniform thickness upwardly, while applying a reactive chemical solution thereto in a counterflow path downwardly, with a substantially full area of exposure of the metal bits to the solution during its upward movement.
