Fluorspar production line and process solutions

Fluorite Ore Production Line and Process Solution

I. Program Overview

This fluorite production line solution for different types of fluorite ore (CaF₂) characteristics, to provide "gravity separation - flotation" joint process, through the differentiation of the separation design to achieve efficient separation of fluorite and barite, quartz, sulfide ores and other veinstones, especially suitable for complex associated fluorite ore sorting.

Second, fluorite beneficiation process flow

1. Crushing system

   • Three sections and one closed-circuit crushing:

     • Jaw crusher (coarse crushing to -80mm)

     • Cone crusher (medium crushing to -20mm)

     • High pressure roller mill (fine crushing to -5mm)

2. Pre-Selected Scrapping System

   • Jigger processing (+2mm coarse grade)

   • 15-30% of waste rock can be pre-collected.

3. Grinding System

   • One stage ball mill (closed circuit with spiral classifier to -0.3mm)

   • Second stage ball mill (closed circuit with cyclone group to -0.074mm 80%)

4. Flotation separation system

   • Fluorite-barite separation:

     • Mixed flotation (oleic acid trap)

     • Separation flotation (pH=8-9, water glass inhibition)

   • Fluorite-quartz separation:

     • Combined inhibitor (water glass + metal ions)

     • Fatty acid-based traps

   • Sulfide-bearing ore processing:

     • Priority flotation of sulfide ores (yellow drug type traps)

     • Re-election of fluorite (adding sulfide ore inhibitor)

5. Concentrate dewatering system

   • High-efficiency thickener (bottom stream concentration ≥65%)

   • Plate and frame filter press (cake moisture ≤10%)

Third, the key equipment configuration

Fourth, the optimization of pharmaceutical system

1. Capture agent system

   • Oleic acid (fluorite main capture agent)

   • Oxidized paraffin soap (auxiliary recovery agent)

   • Yellow medicine (sulfide ore capture agent)

2. Adjusting agent system

   • pH adjuster: Na₂CO₃ (maintain pH=8-9)

   • Inhibitors:

     • Water glass (inhibits quartz)

     • Dextrin (inhibits calcite)

     • Sodium sulfide (inhibit sulfide ore)

V. Fluorite production line beneficiation program advantages

1. Precise sorting technology

   • Compound inhibitor formula (quartz inhibition efficiency increased by 30%)

   • Gradient flotation process (coarse and fine grained graded treatment)

   • Priority flotation technology for sulfide ore

2. Energy-saving design

   • High-pressure roller mill energy-saving 40

   • Utilization rate of return water ≥90

   • Low-temperature flotation chemicals system

3. Stable production guarantee

   • Wear-resistant equipment configuration (cyclone liner, etc.)

   • DCS automatic control system

   • Fault warning system

Typical application cases

1. A quartz-type fluorspar mine in Zhejiang

   • Raw ore CaF₂ 38%, SiO₂ 45

   • Adopting "one coarse, three fine, two sweep" process

   • CaF₂ 97% in concentrate

2. Hunan Barite Fluorite Mine

   • Innovative point: Barite-fluorite sequential priority flotation

   • Concentrate BaSO₄content≤1.5%

   • Annual increase in efficiency of 12 million yuan
