Magnetic separation is used to enrich iron ore samples that demonstrate either para- or ferromagnetic behavior (Flippov et al. 2014). Magnetic separation can be performed on wet or dry material, with wet being a slurry (Flippov et al. 2014). Magnetic separators are broken down into two categories: high and low intensity (Flippov et al. 2014). Low

1. Introduction. The past decades have witnessed tremendous progress made in the magnetic separation technology that have significantly decreased the industrial grade of mined iron ore (Liu et al., 2020, Zeng et al., 2019).However, the extensive energy consumption and high capital costs required in utilization of low-grade …
As Tripathy explains, some types of FDMS can't separate ores smaller than 45µ – frustrating given iron ore particles can be as small as 30µ. Then there are more fundamental problems of magnetic separation. Materials like iron are perfect for FDMS, after all, but what about non-magnetic metals like aluminium, copper or zinc? An …

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 …
