Fluorspar Production Line and Process Solution

Fluorite Ore Production Line Solution is designed for the efficient recovery of Fluorspar (CaF₂) from complex associated ores.

This solution utilizes a "Gravity Separation - Flotation" joint process. It effectively separates Fluorite from Barite, Quartz, and Sulfides, achieving high-grade Acid Spar (CaF₂ ≥ 97%) for chemical and metallurgical industries.

Step 1: Crushing & Pre-Selection

Goal: Reduce ore size and discard waste rock early.

• Crushing: Jaw Crusher (Coarse to -80mm) -> Cone Crusher (Medium to -20mm) -> HPGR (Fine to -5mm).
• Pre-Selection: Using Jig Machine to process +2mm coarse particles. This can discard 15-30% of waste rock, reducing grinding cost.

Step 2: Grinding & Classification

Goal: Liberate Fluorite from impurities.

• Stage 1: Ball Mill + Spiral Classifier (to -0.3mm).
• Stage 2: Ball Mill + Hydrocyclone (to -0.074mm 80%).

Step 3: Flotation Separation (Core)

Specific strategies are used for different impurities:

Step 4: Concentrate Dewatering

• Thickening: High-Efficiency Thickener increases density to ≥65%.
• Filtration: Filter Press produces cake with moisture ≤10%.

Project: Quartz-Type Fluorite Mine

• Raw Ore: CaF₂ 38%, SiO₂ 45%.
• Process: "One Roughing, Three Cleaning, Two Scavenging".
• Result: Concentrate CaF₂ 97% (Acid Grade).

Q1: How do you separate Fluorite from Calcite?

A: Separation is difficult as both contain Calcium. We use specialized inhibitors like Tannin extract or Acidified Water Glass to depress Calcite while floating Fluorite. Controlling pH is crucial.

Q2: What is the difference between Metallurgical and Acid Grade Fluorite?

A: Metallurgical Grade (Metspar) is coarse (+2mm) with 60-85% CaF₂, produced by Jigging. Acid Grade (Acidspar) is fine powder with >97% CaF₂, produced by Flotation for making Hydrofluoric Acid.

Q3: Why use Jigging for pre-selection?

A: Jigging removes barren waste rock early at low cost. This increases the feed grade for the expensive grinding/flotation stage and reduces total energy consumption by up to 30%.
