Steelworks and Slag Processing

The slag produced during the steel manufacturing process contains high amounts of valuable ferrous metals.  The slag is passed through a process whereby the slag is crushed, liberating the valuable ferrous metal.  This ferrous metal is then recovered using heavy-duty magnetic separators.  Typical methods include:

  • Crushed slag is fed onto a heavy-duty Drum Magnet. Magnetic material is attracted to the strong magnetic field and deposited underneath and away from the slag;
  • Replacing a conveyor’s head pulley with a Pulley Magnet. Ferrous metal is attracted to the magnetic field and deposited underneath the conveyor and away from the non-magnetic slag;

Suspending a Permanent Overband or Suspension Magnet (i.e. self-clean or manual clean) or Electro Overband or Suspension Magnet across or over a conveyor.  Metal is lifted off the conveyor belt and either held on the magnet face or automatically discharged.  Commonly Overband Magnets are used to remove large tramp metal that could damage the crusher.
