Lithium pyroxene beneficiation process includes positive/reverse flotation method, magnetic separation method, heavy media beneficiation method and combined beneficiation method depending on the mineral species. Among them, the flotation method is widely used, the magnetic separation method is suitable for ore with iron impurities, and the heavy media beneficiation method is suitable for ore species with coarse crystalline size and little difference in density between lithium pyroxene and other minerals. Lithium beneficiation generally requires crushers, ball mills, classifiers, jig machines, flotation machines, magnetic separators and other equipment. The process and equipment as a whole are not complicated.
