Zircon Sand Beneficiation Production Line and Process Flow

Zircon Sand Beneficiation Production Line Solution is designed for the comprehensive recovery of Zircon from beach sands and alluvial deposits.

This solution adopts a combined process of "Outdoor Wet Roughing + Indoor Dry Cleaning". It integrates multi-stage Gravity, Magnetic, and Electrostatic separation to achieve high-efficiency enrichment, producing a final Zircon concentrate with ZrO₂ ≥ 65%.

Phase 1: Wet Roughing System (Outdoor)

Goal: Discard light silica sand and concentrate heavy minerals.

• Pre-treatment: Trommel Screen removes trash and coarse gravel (2-5mm).
• Gravity Roughing: Spiral Chutes process the sand at 30-40% density. A roughing and sweeping stage increases recovery by 15-20%.
• Wet Magnetic Sep: Removes strong magnetic minerals (Magnetite).
• Cleaning: Shaking Tables produce a coarse Zircon concentrate (ZrO₂ 50-55%).

Phase 2: Dry Cleaning System (Indoor)

Goal: Separate Zircon from Rutile, Ilmenite, and Monazite.

• Drying: Rotary Dryer prepares minerals for electrical separation.
• Magnetic Separation: Dry High-Gradient Magnetic Separator removes weak magnetic minerals (Ilmenite, Monazite).
• Electrostatic Separation: High-Tension Separators separate conductive Rutile (thrown off) from non-conductive Zircon (pinned).
• Final Cleaning: Specialized Magnetic Separators remove any remaining impurities to ensure ZrO₂ ≥ 65%.

• High Recovery: Optimized wet+dry process achieves >90% comprehensive recovery.
• Fine Particle Recovery: Effective for 0.1-0.5mm grains.
• Eco-Friendly: >90% water recycling in wet section, no chemicals used.
• Product Quality: Final Zircon Sand ZrO₂ ≥ 65%.

Q1: How do you separate Zircon from Rutile?

A: Since both are non-magnetic heavy minerals, we use Electrostatic Separation. Rutile is conductive and gets thrown from the rotor, while Zircon is non-conductive and gets "pinned" to the rotor.

Q2: Why is the process split into "Wet" and "Dry"?

A: The Wet Mill uses low-cost gravity separation (water) to remove the massive volume of waste silica sand. The Dry Mill processes the smaller volume of heavy mineral concentrate using electricity and magnetism, which requires dry material.

Q3: What impurities are removed in the final stage?

A: The final cleaning stage often uses high-intensity magnetic separation to remove trace amounts of iron-bearing minerals (like Monazite or weak Ilmenite) from the Zircon to ensure high purity and whiteness.
