Chromite Production Line and Process Solutions

Chromite Production Line Solution focuses on the efficient recovery of Chromite (FeCr₂O₄) using a combined Gravity-Magnetic process.

This solution adopts a technical route of "Multi-stage Classification and Gradient Separation". By optimizing crushing, screening, gravity separation, and magnetic separation, we achieve high-grade chromite concentrate and maximize recovery.

Step 1: Crushing & Screening

Goal: Reduce raw ore size and classify it for different separation methods.

• Crushing: Jaw Crusher (Coarse) and Roller Crusher (Fine) reduce ore size.
• Screening: Circular Vibrating Screen classifies material into two fractions: +5mm (Coarse) and -5mm (Fine).
• Regrinding: +5mm oversize is returned to the crusher for closed-circuit crushing.

Step 2: Gravity Separation (Core Stage)

Goal: Separate chromite based on particle size and density.

• Coarse (+5mm): Processed by Jig Machine. Jigs are efficient for recovering coarse chromite lumps.
• Fine (-5mm): Ground by Ball Mill and classified. -2mm fraction goes to Spiral Chute for roughing and scavenging.

Step 3: Magnetic Purification

Goal: Remove iron impurities and further upgrade the concentrate.

• Spiral chute concentrate enters the multi-stage magnetic separation process.
• Magnetic Separator: Uses Medium/Strong magnetic field to separate magnetic iron minerals from weakly magnetic chromite, improving the Chromium-Iron Ratio.

Step 4: Dewatering & Tailings

• Dewatering: Concentrate is thickened and filtered to obtain the final product.
• Tailings: Dry stacking system with water reuse rate ≥85%.

Q1: What is the typical grade of Chromite Concentrate?

A: Our process typically produces metallurgical grade concentrate with Cr₂O₃ ≥ 45% and a Chromium-Iron ratio ≥ 2.5.

Q2: Why use a Jigger for coarse particles?

A: Jiggers are excellent for processing +5mm coarse particles. They use less water and energy than grinding everything to fine powder, saving significant costs.

Q3: Can you handle low-grade chromite ore?

A: Yes. For low-grade ore, we emphasize Spiral Chutes for low-cost roughing to discard tailings early, followed by Shaking Tables or Magnetic Separators for purification.
