  2. The main problem of fluorite flotation process is the separation from symbiotic gangue (quartz, calcite, barite, etc.).There is also the problem of separation from some sulfide, according to different condition, the flotation method is also different: For fluorite containing sulfide ore, it is common to surface the sulfide ore with xanthate collector, and then flotation fluorite with fatty acid collector. Sometimes in the flotation, a small amount of sulfide mineral inhibitor (such as cyanide) is added to suppress the residual sulfide mineral, so as to ensure the quality of fluorite concentrate. For the separation of fluorite from barite and calcite, oleic acid is generally used as the collector to surface fluorite. In the flotation of fluorite with oleic acid as the collector, a small amount of aluminum salt is added to activate fluorite and dextrin is added to inhibit barite and calcite. The tannin extract and lignosulfonate are effective in inhibiting the complex fluorite minerals which contains more calcite, limestone and dolomite.

  3. Separation of fluorite and quartz, collecting fluorite with fatty acids, sodium silicate as silica inhibitor, sodium carbonate slurry pH adjustment for 8 ~ 9 ° .Dosage of sodium silicate to control well, when a small amount of, fluorite can be activated, the inhibitory effect of quartz is not enough, when a glut of, fluorite also can be inhibitted , in order to add small dosage of sodium silicate , and also achieve the inhibition strengthens of the quartz gangue, often at the same time of adding sodium silicate, add a polyvalent metal ion (e.g., Fe3 +, Al3 +) and alum and aluminium sulphate, etc.In addition, the addition of Cr3+ and Zn2+ ions also had an effect, which inhibited not only quartz but also calcite. The separation of fluorite and barite is usually carried out by mixing and flotation of fluorite and barite, followed by separation. In the process of mixed flotation, oleic acid is used as collector and sodium silicate is used as inhibitor. (1) using dextrin or tannin as inhibitors to inhibit barite and oleic acid for floatation of fluorite; (2) hydroxyl sulfuric acid fat was used to flotation barite, and fluorite concentrate was left in the flotation tank.
