success of dense media recovery by magnetic separation. Whereas magnetic flocculation promotes the recovery of fine ferromagnetic materials, the nature of the effect also promotes ‘stubborn’ entrainment of non-magnetic particles. As a result of this it becomes very difficult to obtain magnetic concentrates with a magnetics content in excess ...
Carrier magnetic separation has been proposed for more effective separation of water and solids from acid mine water to generate very pure water (Feng et al., 2000).As discussed in Chapter 10, dissolved heavy metals like zinc and copper can be recovered from acid mine drainage (AMD) by selective precipitation controlling the pH for the precipitation of specific metals.
