Magnetic separations
The distinguishing feature of the magnetic separation is the presence of long-range, dipole-dipole interparticle magnetic forces that may lead to undesirable microparticle clustering (chaining or amorphous aggregation) and deterioration of the magnetic separation quality if left unchecked (Rosensweig, 2014; Williams et al., 2010).
