Abstract
An apparatus and method for electrowinning metal from particulate waste metal material is provided whereby waste metal material is mixed with an electrolyte to form a suspension. The suspension is separated into portions. A first portion enters the anodic compartment and a second portion is filtered and enters the cathodic compartment where metal is electrowon onto a rotating cathode.
