The barite type fluorite ore is formed by hydrothermal origin in the Ordovician carbonate formation. The main minerals in this type of ore are barite and fluorite, accompanied by a small amount of pyrite, galena, and sphalerite. Ore and other minerals, some deposits have higher quartz content, forming barite-fluorite-quartz deposits. The mineral surface and chemical properties of barite and fluorite in the ore are similar, and the behavior of collectors and inhibitors on the surface of these two minerals are also very similar. It is difficult to effectively recover fluorite ore by gravity separation, so more use Flotation process for separation.

The flotation method of barite type fluorite generally adopts a mixed flotation process, using oleic acid as a collector and water glass as an inhibitor to obtain a mixed concentrate of fluorite and barite, and then flotation and separation of the two . There are two separation methods: one is to inhibit barite from emerging from fluorite, and the other is to inhibit fluorite from emerging from barite.
