  • Byproducts The Phosphate Risk

    Phosphogypsum (or “gypsum”), a radioactive material, is a byproduct of this process. Because it cannot be disposed of in the usual way, gypsum is stored in huge piles, called gyp stacks that cover 600 acres and rise to 200 feet. In the flat topography of Florida, they look like small mountains.

    What is Gypsum? Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite.Gypsum (CaSO 4. 2H 2 O) is very similar to Anhydrite (CaSO 4).The chemical difference is that gypsum contains two waters and anhydrite is without water.
