Beach Sand Heavy Mineral Beneficiation

Beach Sand Process Flow Description

1. The excavator or Loader feeds raw sand to the raw ore bin, and then the electromagnetic vibrating feeder feeds the sand to the vibrating screen.
2. Vibrating screen with one layer screen with 2mm mesh size to remove above 2mm impurities.
3. Below 2mm, go to the magnetic separator by slurry pump for separating magnetite.
4. The output of the magnetic separator is sent to the spiral chute by a slurry pump. Through gravity separation method to remove light minerals.
5. The spiral chute gravity separation plant has two stages: the middling from the first stage spiral chute plant goes to the second stage spiral chute for reprocessing.
6. Send all concentrates from two stages of spiral chute plants to 1st double drum magnetic separator for separating ilmenite.
7. The output of 1st double drum magnetic separator is sent to the Shaking table by a slurry pump for removing light minerals by gravity principle.
8. The Shaking table has two stages: the middling from the first stage shaking table is sent to the second stage shaking table for further processing by a slurry pump.
9. Send all concentrates from the two stages of shaking table plants to the rotary dryer for drying material.
10. After drying, dry materials through the hoist machine to the 2nd double drum magnetic separator to separate ilmenite.
11. Send the other minerals from 2nd double drum magnetic separator to 1st electrostatic separator through the hoist machine for separating rutile, and then use the hoist machine to send the non-conductive minerals(from the 1st electrostatic separator) to 2nd electrostatic separator for separating rutile, the non-conductive minerals (from 2nd electrostatic separator) to 3rd electrostatic separator for separating rutile. Three times electrostatic separation improves the rutile grade.
12. Other minerals from the 3rd electrostatic separator go to the double roller strong magnetic separator via a hoisting machine for separating zircon and monazite.
