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.

Separation or concentration of magnesium-bearing minerals by induced

Particulate glass values contained in the final inorganic fraction from comminuted municipal solid wastes and having the particle size between 10 mesh and 325 mesh are recovered by froth flotation depressing the glass and causing flotation of the gangue using as the beneficiation reagent a water compatible sulfonated hydrocarbon. Glass depression occurs by use of a mineral acid or fluoride ion and maintaining pH of the media less than about 4.

Flotation of inorganic materials from glass using hydrocarbon sulfonates

Particulate glass values contained in a comminuted inorganic fraction are recovered by froth flotation in a substantially sulfate ion free aqueous flotation medium and an amine as the beneficiation reagent.

Flotation separation of glass from a mixture of comminuted inorganic

Particulate glass values contained in the final inorganic fraction from comminuted municipal wastes and having the particle size below 10 mesh, preferably between about 325 to about 20 mesh, are recovered by froth flotation by activating the glass surface with a bi or trivalent metal ion and using as the beneficiation reagent a water compatible sulfonated hydrocarbon.

Particulate glass values contained in the final inorganic fraction from comminuted municipal wastes and having the particle size between about 200 to about 20 mesh are recovered by froth flotation by activating the glass surface with a bi or trivalent metal ion and using as the beneficiation reagent a water compatible sulfonated hydrocarbon.

Particulate glass values contained in a comminuted inorganic fraction and having the particle of a size up to about 10 mesh are recovered by froth flotation using an amine as the beneficiation reagent.
