Maximizing the recovery of fine iron ore using magnetic

Maximizing the recovery of fine iron ore using magnetic

Nov 15, 2016 The recovery of fine iron ore by magnetic separation will decrease with decreasing particle size because the magnetic susceptibility of magnetic particles decreases with a decrease in particle mass. There is an example of an Australian iron-ore operation that introduced beneficiation of fine haematite, -100 m, by using WHIMS2.
