Low intensity separators use magnetic fields ranging between 0.1 Tesla to 0.3 Tesla. Low intensity techniques are normally used on magnetite ore as an inexpensive and effective separation method. High intensity separators employ fields as strong as 1 Tesla to 2 Tesla.

ni The unit of field intensity is Oersteds (Oe) which can be expressed as 10e= 1000 Alm 4;r The magnetic force in a magnetic field is generally conceived and represented by magnetic force lines. For a magnet they are envisaged as running from the south pole to the north pole.

· On the other hand, if your ore contains mainly ferro- and ferrimagnetic minerals for recovery, then a one-stage magnetic separation process with a weak magnet is adequate. Calibration Magnetic tracers are simulants of varying magnetic susceptibilities from weakly paramagnetic to ferromagnetic and assist in calibrating magnetic separators and identifying operational parameters.
