Gypsum Mineral | Uses and Properties

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. Gypsum is the most common sulfate mineral. Gypsum is a very soft mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO 4 ·2H 2 O Rock phosphate is a general term for rock that contains a high concentration of phosphate minerals, which commonly belong to the apatite group. Phosphate rock minerals are the only significant global resources of phosphorus.

ROCK PHOSPHATE: IS IT THE ANSWER FOR YOUR SOIL?

acid soils with any calcium-containing material such as limestone, lime or gypsum always results in a reduction of rock phosphate's ability to become available to the plants. This is because both your soil's pH and exchangeable calcium are raised upon .
