Several attempts have been made by different researchers and technologists to understand the separation behavior of particles in each of these separators treating different types of para-magnetic minerals. Despite all these efforts, these separators are yet to find widespread applications to treat different para …
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 …
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
Liu et al. (2014) found that the optimum conditions for upgrading their iron ore was a primary grind at 60% passing 75 µm and 1.5 T followed by a secondary grind of the coarse concentrate at 71% passing 44 µm and a magnetic field strength of 1.0 T. A WHIMS RK/CSQ-50 × 70 magnetic separator was used to upgrade their ore from a Fe …
