100 TPH Alluvial Zircon & Titanium Minerals Processing Plant in Southwest China

Feed Preparation & Scrubbing:

• Raw sand is fed via a vibrating feeder to a scrubbing machine for intense agitation.
• This step is critical for inland alluvial deposits, effectively disintegrating clay agglomerations and removing surface impurities, ensuring the full liberation of heavy mineral grains.

Concentrate Dewatering & Stockpiling:

• The HMC slurry is first densified using a hydrocyclone and further dewatered in a high-rate thickener.
• The thickened HMC is stockpiled under cover, ready for feeding into the dry processing plant.

Dry Separation Plant (HMC Processing):

• The HMC is uniformly dried in a fuel-fired rotary dryer.
• Stage 1 – Magnetic Separation:
  • A Cross-Belt Magnetic Separator first removes any residual magnetic minerals.
  • Then, a High-Intensity Magnetic Separator (HIMS) is used to separate the strongly magnetic Ilmenite as a final product.
• Stage 2 – Electrostatic Separation:
  • The non-magnetic fraction (containing Zircon and Rutile) is fed into a High-Tension Roll Separator.
  • This separator exploits conductivity differences, attracting the conductive Rutile to the rotor while the non-conductive Zircon is repelled, achieving a clean separation.
• Stage 3 – Cleaning & Purification:
  • Both Zircon and Rutile middlings undergo additional passes through magnetic and electrostatic separators to achieve premium-grade concentrates meeting Chinese national standards (YS/T) for industrial applications.

Primary Concentration (Gravity Separation):

• The scrubbed pulp is distributed to a bank of Reichert Spiral Separators.
• Utilizing differences in specific gravity, the spirals efficiently produce a Heavy Mineral Concentrate (HMC), rejecting the majority of light quartz gangue to tails.

Dust Collection & Tailings Management:

• A fully enclosed conveyor system and a high-efficiency pulse-jet baghouse dust collector maintain a clean plant environment and comply with Chinese environmental regulations.
• Tailings from the spiral circuit are transported to a designed impoundment area for managed disposal and site rehabilitation.
• Process water is clarified in a recycling pond and reused, minimizing freshwater consumption and discharge.

Key Features of the Plant:

• Proven & Efficient Flowsheet: Implements the globally accepted “Gravity-Magnetic-Electrostatic” separation route, optimized for Southwest China alluvial placer deposits.
• High-Quality Products: Produces Zircon concentrate (ZrO₂+HfO₂ >65%), Rutile concentrate (TiO₂ >95%), and Ilmenite concentrate (TiO₂ >50%).
• EPC Turnkey Solution: Provides clients with a single-point responsibility from design to operational handover, ensuring project delivery on time and within budget.
• Emphasis on Environmental Compliance: The plant design strictly adheres to China’s environmental protection policies, featuring comprehensive dust control, water recycling, and responsible tailings management.
• Adapted to Inland Conditions: The process design effectively handles the higher clay content typical of inland alluvial deposits in Southwest China.
