摘要
Methods for selectively enhancing the magnetic properties of fine particles to be recovered or removed by subsequent magnetic separation are reviewed. The comparison of magnetic carrier separation with carrier flotation is also discussed. The influences of physicochemical extent in the adsorption of fine magnetite onto particle surfaces are briefly described. It is concluded that the selectivity of magnetic reagent for the fine particles and the hydrophobic interaction between the particles treated with chemicals and the carriers (e.g. magnetite laden oil or magnetic reagent) depends on factors similar to those in other mineral separation techniques such as hydrophobic agglomeration and shear flocculation. A large number of applications of the magnetic carrier methods in various areas are also introduced.
