2016-11-30  Fluorogypsum (FG) is a byproduct of hydrofluoric acid production. In China, production of one ton of HF can produce four to five tons fluorogypsum. Over 400 million tons of fluorogypsum have been generated by 2010. Most of the generated fluorogypsum is transported to waste dumps stacks requiring large amounts of land and harming the environment.
