The 14 pages that link to Magnetic separation, each with the reason it gives.
Iron oreRelated: It can concentrate magnetite from less magnetic surrounding material.
MagnetiteRelated: Its strong magnetism allows magnetite ore to be separated from much waste rock.
KaolinRelated: High-intensity magnetic separation can remove iron-bearing contaminants from kaolin.
GangueRelated: Magnetic properties can distinguish some ore minerals from associated gangue.
Iron(II,III) oxideRelated: Magnetite can be recovered from mixtures because it is strongly magnetic.
Mechanical screeningCompared with: It distinguishes magnetic properties, not particle dimensions.
