Exploited underground for half a century, anhydrite has not finished revealing its full potential.

Anhydrite, here present, is a calcium sulphate compound that is revealed in finely crystallized or granular mass.
After drilling and blasting, the extracted stone is directed to the crushing plants and then to the micronisation station.
Come discover the manufacturing processes of a product with unsuspected wealth, used in many fields of activity such as the production of cement and concrete, essential materials for the architecture of yesterday and today

À propos du lieu

Anhydrite Lorraine
Route d'Elzange, 57970 Koenigsmacker
  • Moselle
  • Grand Est
At Koenigsmacker, L'Anhydrite Lorraine has been mining white gold since 1970 on the hills east of Canner Creek. This white grey substance composed of calcium sulphate is highly prized by cement and fertilizer manufacturers in particular, and has been mined underground since 1976.
At 2,000 tonnes per day, the site produces 400,000 tonnes of anhydrite each year. The site would still have “significant reserves”.
