Commercially available Fluorspar contains about 0.8 to 1.5% Si02 plus minor trace impurities. The product is minimally hazardous when in its delivered state combined with about 10% maximum water as a filtercake. Dust hazards exist when the product is either dried intentionally or through prolonged open storage.

Global production of fluorspar in 2018 reached 6m tonnes, of which 9.3% was produced in Mongolia. In 2020, Mongolia produced more than 10% of the world's total production of 7.2m tonnes. Excluding its two neighbors, Mongolia has exported small quantities of fluorspar to South Korea on a trial basis before. Export to China first started in 2002.
