For the primary separation, a Magnetic Separator (typically an Induced Magnetic Roll or Rare Earth Roll Separator) removes magnetically-susceptible para and ferro magnetic minerals (e.g. ilmenite, garnet, monazite). The secondary electrostatic separation focuses on separating the remaining minerals (e.g. zircon sand, silica and rutile).

Low intensity magnetic separation pulls out metallic iron and magnetite. The concentrates pass through a high intensity magnetic separator to pull out the ilmenite fraction—46 to 48% TiO2. The non-magnetic fraction is subjected to high intensity electrostatic separation which removes the high grade rutile—94-95% TiO2.

The distinguishing feature of the magnetic separation is the presence of long-range, dipole-dipole interparticle magnetic forces that may lead to undesirable microparticle clustering (chaining or amorphous aggregation) and deterioration of the magnetic separation quality if left unchecked (Rosensweig, 2014; Williams et al., 2010).

magnetic product concentrate [4]. These two products (magnetic and non-magnetic) will be processed in two different circuits in parallel. The ilmenite concentrate (WHMag) will undergo a series of dry electrostatic and magnetic separations to first obtain a pure ilmenite concentrate (ilmenite 1) which is highly conductive and highly magnetic.
