Quartz-type fluorite ore is mainly composed of fluorite (content up to about 85%) and quartz. At the same time, there are also small amounts of calcite, barite and sulfide. This type of fluorspar ore mainly uses flotation method.

In production, quartz-type fluorite-type ores usually adopt a process of grinding and roughing once, and then grinding and re-grinding the coarse concentrate for multiple times. The pharmaceutical system often uses sodium carbonate as an adjuster, and is adjusted to Alkaline to prevent the activation of quartz by polyvalent cations in the water, use fatty acids as collectors, add an appropriate amount of water glass to inhibit silicate gangue minerals, and control the amount of water glass (a small amount has a negative effect on fluorite) Activation, fluorite will be inhibited in excess).

According to the distribution characteristics of useful minerals, quartz-fluorite ore can be mainly divided into coarse-grained distribution There are two types: fine-grained cloth and fine-grained cloth. The two types are different in the flotation separation process.

Coarse-grained ore: Fatty acid collectors are often used, the slurry regulator is sodium carbonate, the quartz inhibitor is water glass, and it is processed through a coarse poly-finishing process. That is to say, high-quality fluorspar concentrate can be obtained;

Fine-grained ore:The flotation reagents are the same as those of coarse-grained quartz fluorspar ore, but due to the The particle size of the target mineral is relatively fine, so the grinding needs to be strengthened, and a staged grinding and sorting process is adopted.

The above quartz typefluorite ore flotation process’s introduction, in actual mineral processing plants, the structure of fluorite ore is complex and needs to be determined according to the properties of the ore. Therefore, it is recommended to determine the suitable fluorspar mineral processing process through mineral processing tests.
