ABSTRACT:
In the method described fluid containing magnetizable particles is introduced into a separating chamber containing a fluid-permeable mass of magnetizable material and held therein for a finite length of time. During this time the magnetizable material is moved into a magnetic field where the fluid is drained from the magnetizable material leaving magnetizable particles entrained in this material. This draining may be achieved either by providing relative movement between the separating chamber and the magnetizable material or by discharging the fluid from the separating chamber. The magnetic separator described comprises a chain of separating chambers, and associated masses of magnetizable material, which are moved continuously through a separating zone in which a magnetic field is established by a magnet. In this zone each mass of magnetizable material is drained and, outside this zone, the magnetizable particles entrained in the magnetizable material are removed by flushing.
