04/10/2018 These filaments are chosen to match the size of the feed particles in order to optimize the magnetic forces. The iron ore feed, in fluid (usually water) slurry, is passed down through the container. The fluid and non-magnetic particles pass easily through the relatively open structure of the matrix. The trapped magnetic particles are easily washed out when the applied field is reduced to zero. Magnetic separators of this type are useful for the concentration or removal of fine magnetic ...

For example, magnetite iron ore containing only about 4% Fe (beach sands or ancient beach sands) to 15% Fe (iron ore formations) and oxidized iron ore of only about 10% Fe (previously mine waste) to 20% Fe (oxidized iron ore formations) are reported to be utilized. They are first crushed and the coarse particles pretreated using roll magnetic separators. The magnetic product of roll magnetic separators

magnetic separation. Dry Magnetic Separation of Iron Ore: There are many inherent advantages in processes that utilize dry magnetic separation to beneficiate iron ore. Wet concentration of magnetite ore, in comparison, re- quires 500 to 1000 gal of water per ton of concen- trate produced. This means extensive use of water

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 µm, by using WHIMS2. The WHIMS feed was deslimed at 10 µm, with the –10 µm ...

magnetic separation is a relatively simple, no-drying, energysaving technology. However, the - limitations of the existing magnetic equipment result in lower mineral separation accuracies for fine-grained steel slag [10].
