In 1923 a contract was won to supply 2,000 tons per month of Anhydrite to ICI at Billingham to produce ammonium sulfate. This enabled the company to invest in new mining equipment to increase productivity. However, this only lasted until 1925 after 40,000 tons had been provided when ICI found alternative sources.

15.10.2022How does anhydrite turn into gypsum? Anhydrite converts to gypsum when exposed to water, which creates a volume increase that destroys any planar features in the beds. The reverse is also possible—anhydrite can be created when gypsum is dehydrated. Both minerals display vitreous luster and are white in color and streak. How common is

When gypsum is heated, water is driven from its crystal structure to produce anhydrite. Anhydrite is commonly known as Plaster of Paris, because thick deposits of gypsum occur in the Paris Basin. When Plaster of Paris is mixed with water, it forms a paste that can be easily shaped and that hardens into solid gypsum.
