  Pulsating high-gradient magnetic separation of fine hematite …

  200981 · Pulsating high-gradient magnetic separation (PHGMS) of fine hematite from tailings was studied using a pilot PHGMS separator to investigate the possibility of its application in industry. The results of this investigation indicate that PHGMS is effective for recovering fine hematite from the tailings and greatly improved the separation …

  Physical separation of iron ore: magnetic separation

  202211 · This chapter introduces the principle of how low-grade iron ores are upgraded to high quality iron ore concentrates by magnetic separation. Magnetite is the most magnetic of all the naturally occurring minerals on earth and can be readily extracted by low-intensity magnetic separators from magnetite ores. On the other hand, oxidized iron ores ...

  A wet belt permanent high gradient magnetic separator for purification ...

  2016810 · This pilot-scale separator also produced a non-magnetic product assaying 0.041% Fe 2 O 3 at an iron removal rate of 58.70% (nearly 96% for magnetic minerals) from a feldspar ore assaying 0.068% Fe 2 O 3. It was concluded that this HGMS separator has provided an effective method for the removal of magnetic impurities from non-metallic ores.

  Assessing the performance of a novel pneumatic magnetic separator for ...

  202091 · Dwari et al. (2013) used a combination of dry and wet magnetic separation methods to upgrade a low-grade siliceous iron ore with magnetite, hematite, and goethite as major iron minerals. The study showed that for particles finer than 200 µm, the separation methods produced a magnetic concentrate with 67% iron and iron recovery of 90%.

  DRY MAGNETIC SEPARATION OF MAGNETITE ORES

  5  · The optimum grade that could be obtained from single-stage dry magnetic separation was 35.52% Mn, and with a Mn:Fe ratio of 1.77, and 44% Mn recovery in the case of sample 1; whereas, a 33.75% Mn grade, with a Mn:Fe ratio of 1.66 at Mn recovery of 44% was reported for Sample 2. It was observed that both samples had a similar input …
