Fluorite Ore Processing

The main component of fluorite (fluorspar) is CaF₂. Fluorite ore processing mainly includes gravity separation and flotation.

Different fluorite ore types, embedded particle sizes, and ore properties require customized processing plants and equipment. We provide tailored solutions based on specific ore characteristics.

Fluorite Ore Beneficiation Process

1. Gravity separation is mainly used to extract coarse-grained massive metallurgical grade fluorite ore. It is primarily completed by a jig concentrator, achieving remarkable material separation effects.

2. Flotation separation is mainly used to produce high-quality fluorite concentrate. The key challenge in fluorite flotation is separating gangue minerals such as quartz, calcite, and granite. Based on different gangue minerals, fluorite ore beneficiation can be divided into the following four types:

• Quartz-fluorite type ore: Mainly composed of fluorite (about 80%-90%) and quartz, with only a small amount of calcite, barite, and sulfide. The key is to reduce silicon in concentrates. (Main process: crushing-grinding-roughing-rough concentrate regrinding-multiple separation)

• Calcite-fluorite type ore: Main minerals are fluorite and calcite (content up to 30%), some containing a small amount of quartz. Sometimes it forms quartz-calcite-fluorite type ore, which is refractory. (Main process: crushing – grading – jigging – grinding – roughing – multiple flotation)

• Sulfide fluorite type ore: Mainly uses flotation. A small amount of sulfide ore inhibitor (such as cyanide) is added to suppress residual sulfide, ensuring fluorite concentrate quality. It enables comprehensive recycling of valuable metals while producing high-quality fluorite products. (Main process: crushing – grinding – preferential flotation of sulfide minerals – tailings flotation of fluorite – rough concentrate multiple separations)

• Barite-type fluorite ore: Barite and fluorite in the ore have similar surface and chemical properties, so flotation is often used.

• Electromagnetic vibrating feeder

• Ball mill

• Spiral classifier

• Conditioning tank

• Flotation machine

• Thickener

• Slurry pump

• Vacuum disk filter

1. Crushing and screening: Due to varying fluorite mine properties in different regions, some plants use a three-stage closed-circuit crushing process, while others use a three-stage open-circuit process.

2. Grinding: A two-stage grinding process is usually adopted. The ball mill combined with a spiral classifier forms a closed-circuit grinding system, capable of grinding to the required particle size.

3. Flotation separation: Fine-grained minerals are separated, enter the mixing tank to be mixed with flotation agents, and then enter the flotation machine for separation.

4. Dewatering: The material enters the thickener for concentration and clarified water recycling. Then, the concentrate is sent to the vacuum disc filter via a slurry pump, where it is dehydrated into a filter cake.
