separation of silica from magnetite

separation of silica from magnetite

Jun 01, 2020 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).
