3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Specific susceptibility The magnetic moment produced by a unit mass of material particles in an external magnetic field of unit strength. 3.2 Magnetic separation The method of sorting out a certain magnetic substance from the selected materials by means of non-uniform magnetic force. Note. Magnetic separation covers four functions, namely magnetic enrichment, magnetic separation, magnetic impurity removal and magnetic flocculation. 3.3 Magnetic concentration The non-uniform magnetic force is used to enrich the magnetic substances in the selected materials with magnetic differences. 3.4 Magnetic separation The non-uniform magnetic force is used to separate the magnetic substances in the selected materials with magnetic differences. 3.5 Magnetic impurityremoval Use non-uniform magnetic force to remove the magnetic substances in the selected materials with magnetic differences. 3.6 Magnetic flocculation Use non-uniform magnetic force to make the magnetic material in the selected materials flocculate into a group.
