In view of the various reasons for the loss of fine grain scheelite in ore dressing, from different angles, the beneficiator put forward some selection methods for fine minerals, such as flotation column flotation, vacuum or decompression flotation, selective flocculation flotation, carrier flotation, two liquid flotation, electrochemical flotation, shear flocculation and so on, but it should be practical in practice. The effect is not obvious in the use of the process.

China is recognized as a fluorite resource country, producer, and exporter in the world. The reserves, extraction volume and export volume rank first in the world. Fluorite is the most important mineral in fluoride. It has unique physical and chemical properties, and has a wide range of uses. It plays a decisive role in industrial development. However, China's single-type fluorite deposits have small reserves, and the rich tungsten ore with a CaF2 grade of more than 65% is less than 23% of China's fluorite reserves. Most of the fluorite resources are associated minerals and are mainly associated with scheelite.
