Removal of magnetic minerals such as hematite, limonite, and biotite from raw materials utilizing a strong magnetic field of magnetic separator. 3. Spiral Chute Re-selection. The non-magnetic mineral impurities in quartz sand are separated by the double action of gravity and the centrifugal force of spiral chute. 4. Flotation Method
Materials smaller than 1mm are fed to the feeding port of the spiral chute by sand pump. 3.Separation: spiral chute, shaking table, magnetic separator. Gravity separation mainly removes light minerals. The medium ore and concentrate in the spiral chute enter the shaking table together for separation, and the tailings are discharged together.
