MEDIATING ELECTROSTATIC SEPARATIONS

摘要

A methods and apparatus for separating polymer mixture comprising providing a feed mixture (205), adding a charging media (230), triboelectrically charging the mixture with the media (210) and separating the polymer mixture into at least two components (220, 225), wherein a portion of the particulate media is recovered using a recovered using a recovery process and a functional additive for the media is selected based on compatibility with the recovery process.
