Coastal Placer Production Line and Process Solution

Coastal Placer Production Line Solution is designed for the comprehensive recovery of Ilmenite, Zircon, Rutile, and Monazite.

This solution adopts a combined process of "Gravity Separation - Magnetic Separation - Electrostatic Separation". By utilizing the differences in density, magnetism, and conductivity, we achieve high-grade concentrates for each mineral type from beach sands.

Step 1: Pre-treatment (Screening)

Goal: Remove trash (roots, shells) and coarse gravel.

• Equipment: Trommel Screen.
• Action: Double-layer screening ensures only sand-sized particles (< 2mm) enter the gravity circuit.

Step 2: Wet Concentration (Gravity)

Goal: Discard light Silica Sand (Quartz) to produce Heavy Mineral Concentrate (HMC).

• Roughing: Spiral Chute Group. Uses gravity and centrifugal force to separate heavy minerals. Low energy cost.
• Cleaning: Shaking Table. Improves the grade of the HMC.
• Wet Magnetic Sep: Removes strong magnetic minerals (Magnetite) early on.

Step 3: Dry Mill Separation (Magnetic & Electrostatic)

Goal: Separate the heavy minerals from each other based on physical properties.

Typical Final Concentrate Grades

• Ilmenite Concentrate: TiO₂ ≥ 46%
• Zircon Sand: ZrO₂ 65% (High Purity)
• Rutile Concentrate: TiO₂ ≥ 95%
• Monazite: Rare Earth Oxides recovered.

Q1: How do you separate Rutile from Zircon?

A: Both are heavy and non-magnetic, so gravity and magnetic separation can't separate them. We use Electrostatic Separation: Rutile is conductive and gets thrown from the rotor, while Zircon is non-conductive and "pinned" to the rotor.

Q2: What is the difference between Wet Mill and Dry Mill?

A: The Wet Mill uses water and gravity (Spirals) to remove the bulk of silica sand (tailings). The Dry Mill uses electricity and magnetism to separate the valuable heavy minerals from each other. The Dry Mill requires the feed to be dried first.

Q3: Do I need chemicals?

A: Generally, no. This is a physical separation process (Gravity/Magnetic/Electrostatic) and is very environmentally friendly compared to flotation.
