WHIM is the short acronym for Wet High Intensity Magnetic Separation. At present, most U.S. iron raw materials are produced from magnetic taconites, which are ground to a nominal minus 270 mesh (53 micrometers), beneficiated by wet low-intensity magnetic separation, and pelletized. The taconite ore bodies generally contain 19 to …
The study of beneficiation indicators of the magnetic separator was carried out using iron ore of the Bapy deposit, which is mono-mineral magnetite. For the study, mixtures of the minus 0.1 mm class were selected with the iron content α = 50% and α = 40%. ... After the study of different size iron ore separation, a reasonability of the DMS ...
Calcium stannates were non-magnetic materials and Fe 3 O 4 was ferromagnetic, then tin-bearing compounds could be separated from iron oxides during a magnetic separation process. However, Ca 2 Fe 2 O 5 was found in the roasted products when roasting temperature was higher than 900 °C, which was adverse to the …
Whatever its flaws, this technique is cheap and straightforward enough to ingratiate itself with mining engineers the world over. According to work by Research and Markets, the appetite for magnetic separation is expected to reach nearly $1bn by 2025, up from just $685m in 2019. Even so, wet magnetic separation is far from perfect.
SLon magnetic separators utilise the combined force fields of magnetism, pulsating fluid and gravity to continuously beneficiate fine weakly magnetic minerals. They possess the advantages of high efficiency, low operative cost and high reliability. Until now there were about 600 SLon magnetic separators widely applied in processing oxidised iron ores, …

The MAGQUIP semi counter current type wet drum separator can be of two or more typically three stage configurations as typically found in the final cleaning "finishing" stage of iron ore concentration post "cobbing" [primary crushing] and "roughing" [secondary milling] stages and will product the final high grade magnetic concentrate.
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.
