Fluorite ore beneficiation process


Fluorite ore is an important mineral resource, which plays a very important role in metallurgy, chemical industry and other industries and fields. As a mineral resource, fluorite ore can be used directly without treatment, so most of fluorite The ore needs to be processed and purified before it can be used. So what is the beneficiation process of fluorite ore? Yantai Rhyther Mining Machinery Factory is here to introduce the beneficiation process of fluorite ore for the reference of related parties!

The beneficiation process of fluorite ore needs to be formulated according to various factors such as the nature of the ore and the grade of the concentrate required by the customer. Generally, the beneficiation of metallurgical-grade fluorite concentrate only needs to be hand-selected and re-selected. For the acid-grade chemical industry The preparation of fluorite concentrate powder needs to be obtained by flotation. The process is a combination of manual separation, gravity separation, and flotation to process fluorite ore, which has a strong representativeness.

Brief introduction of fluorite beneficiation process:

1.Crushing and screening process

Fluorite is fragile and fragile. The crushing process adopts a simple jaw crusher to avoid excessive powdery fluorite ore. The screening adopts a circular screen with high screening efficiency and thorough screening, and the crushed products are strictly In the screening operation, the crushed fluorite ore is divided into three sizes: +30mm, 8-30mm, and 0-8mm.

2.Hand selection process

Hand selection means manual hand picking and discarding of large gangues, and picking out coarse-grained fluorite concentrate. Manual selection is generally carried out on a horizontal belt conveyor with adjustable speed, and qualified concentrates are selected by manual picking method.

3.The gravity separation

The gravity separation process uses a jig to center, and the fine-grained fluorite ore is gravity-dressed, and the granular concentrate is mixed with the hand-dressed concentrate as a coarse-grained metallurgical grade fluorite product. The tailings and hand-selected tailings are mixed into the grinding process.

4.Flotation process

Fluorite belongs to easy-float ore. The flotation process includes grinding, grading, flotation and other processes. The flotation of fluorite ore is mainly based on the separation of fluorite and gangue flotation. Fluorite flotation The collectors used are usually: fatty acids such as oleic acid or oxidized paraffin soap and their soaps as collectors, and the best flotation temperature is 30-35 degrees. Sodium carbonate is used as regulator and water glass as inhibitor during flotation, and the best flotation temperature is 30-35 degrees.


As acid-grade fluorite concentrate requires high grade, the flotation process is generally designed with multiple beneficiation processes, at least not less than 3 times of beneficiation. This process uses 6 times of beneficiation, and the grade of fluorite concentrate is guaranteed to be more than 97%.

The beneficiation process of fluorite ore needs to be determined according to the nature and purpose of the fluorite ore. For the beneficiation of coarse-grained contiguous fluorite, the method of manual separation and gravity separation is generally used to obtain metallurgical grade fluorite concentrate. The flotation method is generally used to prepare high-quality fluorite powder from fine-grained embedded low-grade fluorite ore.
