Current status of fluorite processing technology
The mineral processing methods of fluorite mainly depend on the application of fluorite, which can be roughly divided into manual separation, gravity separation and flotation, among which the flotation method is the most widely used.
Flotation agents commonly used anionic collector.Fatty acids have strong collecting effect when used as collectors.In order to improve the taste of fluorite concentrate, it is very important to choose effective inhibitors, such as water glass, sodium metaphosphate, lignosulfonate, dextrin, tannic acid, oxalic acid, etc.Flotation slurry is often added in the form of combined agents, such as sulfuric acid + sodium silicate (also known as acidified water glass), which has obvious effects on the inhibition of calcite and silicate minerals.

Sulphide - fluorite shape: the ore is mainly composed of lead and zinc minerals, and fluorite is the associated mineral. The mineral processing method is mainly floatation. The sulphide is first floatated, and then the fluorite is selected.

Beneficiation process
Quartz - fluorite type ores: raw ore crushing - grinding - rough dressing - coarse concentrate grinding - multiple selection;
Calcite - fluorite type ore: raw ore crushing - grading - jigging - grinding - rough - multiple selection;
Sulfide-fluorite type ore: raw ore crushing - grinding - preferential flotation sulphide mineral - tailings flotation - fluorite - fluorite coarse concentrate for many times.
