Physical separation of iron ore: magnetic separation
Laboratory tests have shown that dry magnetic separation is not as efficient as wet magnetic separation in the fine particle size ranges. 9.6. Summary. The majority of iron ores occurring naturally on earth are low grade and need to be upgraded prior to use in metallurgical processes. Magnetic separation is the most important method for ...

Wet High Intensity Magnetic Separation
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 25 …

Magnetic Bead-Based Nucleic Acid Isolation | SpringerLink
Magnetic separation is a technique used to separate paramagnetic or superparamagnetic particles (of size less than the macroscale range) from a suspension by applying an external magnetic field. Due to induced spin, paramagnetic particles act like tiny magnets and interact with an externally applied magnetic field (Akbarzadeh, 2012 ).
