Early domestic production of cryolite generally used fluorite as raw material. The world fluorite resources are mainly distributed in China, Mongolia and Thailand in Asia, Mexico, the United States and Canada in North America. China is a country with large reserves and production of fluorite in the world (the proved reserves account for more than 50% of the world's total reserves) and good grade. Rich fluorite resources have laid a solid foundation for the development of cryolite in China.

At present, the general office of the State Council has issued the notice on taking comprehensive measures to control the mining and production of refractory clay fluorite, which implements the dual total amount control of mining and production of fluorite. Cryolite production began to follow the path of comprehensive utilization and development of fluorine resources. The current processes and production raw materials include:

1. Technology of producing high quality white carbon black from cryolite by sodium fluosilicate method

The project of producing high-quality white carbon black from cryolite by sodium fluorosilicate method can produce high molecular weight cryolite and high-quality white carbon black by using sodium fluorosilicate, a by-product of phosphate fertilizer industry.

2. Technology of producing cryolite by clay brine method

3. Preparation of cryolite from ammonium fluoroaluminate

This production process can use ammonium fluoroaluminate, a waste from aluminum processing industry, to produce cryolite products.

4. Production technology of regenerated cryolite

This process uses the waste of electrolytic aluminum industry to produce cryolite
