Abstract
A process and apparatus for separating metallic from nonmetallic components in a mixture are disclosed. The process and apparatus rely upon the combination of prefractionation by sedimentation, preferably centrifugal sedimentation, followed by final concentration in a laminar flow process, preferably employing a spiral separator and one or more vibrating tables, to recover substantially all metal components of the mixture.

A process for separating metallic components from nonmetallic components in a mixture comprising mixing the mixture with water and subjecting the mixture to prefractionation by sedimentation to produce a heavy output fraction substantially comprising water, metallic components and heavy nonmetallic components and a light output fraction substantially comprising water, light nonmetallic components and entrained fibers and subsequently subjecting the heavy output fraction to laminar flow stratification fractionation to produce a heavy output fraction substantially comprising metallic components and a light output fraction substantially comprising nonmetallic components.
An apparatus for separating metallic components from nonmetallic components in a mixture, comprising agitator means including a water inlet, agitator, means for addition of a mixture of metallic and nonmetallic components and outlet means, hydrocyclone having an inlet for receiving said mixture connected to the outlet means of said agitator means and an outlet for removal of a light output fraction substantially comprising light nonmetallic components and entrained fibers including light fibers, and an outlet for removal of a heavy output fraction substantially comprising metallic components and heavy nonmetallic components, said outlet for said heavy output fraction being connected to the inlet of a helical trough stratification separator which has at least two outlet means, at least one outlet means of said helical trough connected directly to inlet means of at least one vibrating table, said at least one vibrating table providing a heavy output fraction substantially comprising metallic components through outlet means on said vibrating table.
