METHOD AND DEVICE FOR MUTUALLY SEPARATING METALLIC COMPONENTFROM NONMETALLIC COMPONENT OF MIXTURE AND DIFFERENT NONMETALLIC COMPONENT AS OCCASION DEMAND

摘要

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.
