Abstract
A method for the separation of magnesium-bearing ore particles containing an exposed magnesian-rich mineral on the surface from the lean ore particles containing a lesser surface area of the exposed magnesian mineral which comprises conditioning the ore with a coupling agent of hydroxyquinoline; irradiating the conditioned ore to excite and induce fluorescence; and separating the magnesian-rich mineral from the lean ore particles by detecting the difference of the fluorescence intensity.
