### PULSATING HIGH GRADIENT MAGNETIC SEPARATION FOR ...

In fact, high gradient magnetic separation (HGMS) can produce a sufficiently strong magnetic force for impurity particles to separate. But the mechanical entrainment onto magnetic matrix and lowefficiency limited their applications (Svoboda et al., 2003). Therefore, for intensifying the separation effect, some

### Working principle and application of magnetic separation ...

This separation process not only can be achieved via the utilization of high magnetic field gradient, but also, in most cases, low magnetic field gradient with magnitude less than 100 T m −1 is equally feasible. It is the aim of this review paper to summarize the usage of both high gradient magnetic separation and low gradient magnetic separation (LGMS) techniques in this area of research.
