Gypsum | Common Minerals
Gypsum is a very soft mineral that is easily identified by its hardness, cleavage, and solubility in water. Typically clear to white, gypsum may be colored reddish to brown or yellow if impurities are present. Most gypsum occurs in its massive form, as layers of rock that often intercalate layers of shale, limestone, or dolostone.

Lithium Production Processes
The gypsum–limestone process was later utilized by Büyükburç and Köksal 69 to extract lithium from a boron clay containing 0.2% Li. A mixture of the clay with these additives was sintered at 915 °C for 110 min and the calcine was then subjected to water leaching at room temperature, resulting in approximately 88% Li recovery.
