Product Details

Ilmenite Processing Plant (Gravity + Magnetic Separation)

Ilmenite (FeTiO₃) is the primary commercial source of titanium dioxide (TiO₂). Because it possesses both a high specific gravity and weak magnetic properties, a "Gravity + Magnetic Separation" combined process is the absolute industry standard for achieving high commercial grades.

However, the processing strategy differs drastically depending on the ore source. Our Ilmenite Ore Dressing Solutions provide scientifically tailored flowsheets for both Alluvial (Sand) Ilmenite and Igneous (Hard Rock) Ilmenite. By optimizing equipment configurations for your specific deposit type, we ensure maximum TiO₂ recovery, stable operation, and highly efficient energy consumption.

Customized Flowsheets: Sand vs. Hard Rock

We design your plant specifically around the geological characteristics of your titanium deposit.

Flowsheet 1: Alluvial (Sand) Ilmenite

Because sand deposits are naturally liberated, no crushing or grinding is required.

Washing & Screening: Raw sand is fed into a Trommel Screen or Rotary Scrubber (Capacity: 50-300 t/h) to break up clay balls and remove barren roots and oversize gravel.
Gravity Enrichment: The -2mm heavy sand is pumped to an array of Spiral Chutes for roughing and sweeping. Spirals quickly discard light silica sand, producing a heavy mineral concentrate.
Magnetic Purification: The heavy concentrate passes through a Multi-Gradient Magnetic Separator. Low-intensity magnets first remove highly magnetic magnetite, followed by high-intensity magnets (0.8 - 1.5 Tesla) which selectively pull the weakly magnetic ilmenite into a pure TiO₂ concentrate.

Flowsheet 2: Igneous (Rock) Ilmenite

Hard rock requires an extensive comminution circuit to liberate the titanium crystals.

Crushing & Grinding: Raw rock undergoes primary and secondary crushing (Jaw & Cone Crushers). The crushed ore enters a Ball Mill and is ground down to a fine -0.3mm to achieve full mineral liberation.
Gravity Pre-Enrichment: The milled slurry is pumped to Spiral Chutes or Mineral Jigs to discard the bulk of the non-valuable light gangue rock, reducing the load on downstream equipment.
Magnetic Purification: The enriched concentrate is processed through a Multi-Gradient Magnetic Separator with an adjustable field strength to perfectly isolate the ilmenite from non-magnetic heavy minerals (like rutile or zircon).

Frequently Asked Questions (FAQ) About Titanium Processing

Q1: Why do I need a "Multi-Gradient" Magnetic Separator for Ilmenite?

A: Ilmenite sand is rarely pure; it is almost always mixed with Magnetite (highly magnetic) and other heavy minerals like Zircon or Rutile (non-magnetic). A multi-gradient separator uses a weak magnetic roller first to pull out the trash magnetite. Then, a highly powerful roller (0.8 - 1.5 Tesla) pulls out the weakly magnetic ilmenite, leaving the non-magnetic zircon/rutile behind. A single-strength magnet cannot perform this complex separation.

Q2: What is the main advantage of this specific flowsheet?

A: Cost efficiency. By using low-energy Spiral Chutes to discard up to 70% of the barren waste sand immediately (gravity pre-enrichment), we drastically reduce the volume of material that needs to be processed by the more expensive magnetic separators. This "smart scaling" saves massive amounts of electricity and equipment capital.
