Antimony Ore Processing

Antimony ore can be classified into antimony oxide and antimony sulfide. The main methods for its beneficiation are hand selection, gravity separation, and flotation.

Antimony ore beneficiation can be achieved through a combination of hand separation, gravity separation, and flotation techniques. Our antimony ore processing plants and equipment are designed to have strong adaptability and high recovery rates.

Antimony Beneficiation Process

  1. Hand Selection: Antimony ore can be easily hand-selected due to the distinct differences in color, luster, and shape between antimony-containing minerals and gangue. Prior to manual separation, ore washing is done to remove impurities, followed by crushing of the stibnite ore.
  2. Gravity Separation: Gravity separation is suitable for processing antimony oxide ore and coarse-grained stibnite. It can also be used for pre-selection and enrichment of antimony sulfide ore prior to flotation. Gravity separation equipment such as spiral chutes, shaking tables, and jig concentrators are commonly used for this method.
  3. Flotation Separation: Flotation is effective for fine-grained disseminated antimony sulfide ore. Single flotation method is used for processing single antimony ore. The combined gravity separation-flotation method is suitable for treating antimony ore with uneven particle size, such as polymetallic sulfide ores containing antimony, tungsten, gold, arsenic, lead, zinc, mercury, or other elements. The purpose of gravity separation is to discard waste rock and reduce the cost and equipment investment for subsequent flotation.

Antimony Ore Processing Plant

This is a 300TPD sulfide antimony flotation processing plant that includes the following equipment:

  1. Chute feeder
  2. Jaw crusher
  3. Fine jaw crusher
  4. Vibration screen
  5. Electromagnetic feeder
  6. Ball mill
  7. Slurry pump
  8. Spiral classifier
  9. Flotation machines
  10. Thickener
  11. Disc vacuum filter machine
  12. Spiral chute
  13. Shaking table
  14. Cone thickener
  15. Plate filter press

The process follows a free flow design. Here is a brief overview of the equipment and their functions:

  • Chute feeder: Automatically feeds stones to the jaw crusher.
  • Jaw crusher: Crushes large stones into smaller ones.
  • Fine jaw crusher: Further crushes the output from the jaw crusher into fine sands.
  • Vibration screen: Sieves particles above 20mm, sending them back to the fine jaw crusher, while particles below 20mm go to the storage bin.
  • Storage bin + electromagnetic feeder: Automatically feeds materials to the ball mill.
  • Ball mill: Grinds the fine sands to a size of 0-1mm, combined with the spiral classifier.
  • Spiral classifier: Ensures the final product size is 0-0.074mm.
  • Slurry pump: Transports the overflow from the spiral classifier to the flotation machine.
  • Flotation machine: Extracts antimony concentrate using chemicals.
  • Thickener: Processes the antimony concentrate.
  • Disc vacuum filter machine: Obtains dry final products from the antimony concentrate.
  • Spiral chute: Recovers antimony from the flotation machine tailings.
  • Shaking table: Concentrates the antimony recovered from the spiral chute.
  • Cone thickener: Processes the tailings from the spiral chute and shaking table.
  • Plate filter press: Recycles water from the tailings.

Please note that the layout and capacity of this flotation plant can be customized based on specific requirements and mine conditions.
