Gypsum - Wikipedia Gypsum is deposited from lake and sea water, as well as in hot springs, from volcanic vapors, and sulfate solutions in veins. Hydrothermal anhydrite in veins is commonly hydrated to gypsum by groundwater in near-surface exposures. It is often associated with the minerals halite and sulfur. Gypsum is the most common sulfate mineral. Crystal habit: Massive, flat. Elongated and generally prismatic crystalsCrystal class: Prismatic (2/m), H-M symbol: (2/m)Mohs scale hardness: 1.5–2 (defining mineral for 2)Crystal system: MonoclinicByproduct Gypsum - ASTM International It is suggested that the United States use more of the increasing tonnages of byproduct gypsum for its traditional uses of wallboard, plaster, and as a set retarder in cement. Other high-tonnage uses are offered, such as cellular foamed gypsum for insulation, road construction, gateway supports in coal mines, and its potential as the largest sulfur resource in the world.
