Dry Magnetic Separation of Iron Ore of the Bakchar Deposit

Magnetic separation is the only effective way of separating the valuable components of iron ore from the diamagnetic inclusions so far as the extractable iron compounds have a high magnetic susceptibility (as a rule, 20– 90·107 m3/kg8) In mining industry the technology of preliminary minerals concentration with selfpropelled01/01/2015· Challenges and recent advances in magnetic separation As highgrade iron ore resources become less and less due to the rapid increase in steel production, iron ore beneficiation is becoming more and more important The complexity of new ores also makes the task more and more difficult Recent advances in magnetic separation are summarized below 951 Development of large magneticDevelopments in the physical separation of iron oreThe 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 ironore operation that introduced beneficiation of fine haematite, –100 µm, by using WHIMS2 The WHIMS feed was deslimed at 10 µm, with the –10 µmMaximizing the recovery of fine iron ore using magnetic
