The gravity sedimentation of three narrow-sized fractions of suspensions of magnetite particles exposed to
magnetic fields ranging from 0 to 180 x 10-4 T was studied experimentally. At volumetric solids concentrations in excess
of 15%, the magnetized suspensions of magnetite with size fractions ranging from -75 to +38 μm settled more slowly than
the non-magnetized suspensions. However, owing to relatively weak magnetic interaction, the sedimentation of the magnetized
and non-magnetized -38 μm size fractions was similar.
