gypsum
Gypsum deposits are located in the center of the Michigan basin. It is only mined at places where the gypsum is near the surface, while at others it is buried by more than 1200 feet of rock (see map below). Gypsum beds are seldom more than 20 feet in thickness.

Gypsum
Gypsum. Gypsum is a mineral found in crystal as well as masses called gypsum rock. It is a very soft mineral and it can form very pretty, and sometimes extremely large colored crystals. Massive gypsum rock forms within layers of sedimentary rock, typically found in thick beds or layers. It forms in lagoons where ocean waters high in calcium and

Gypsum production process. Gypsum ore, from quarries and underground mines, is crushed and stockpiled near a plant. Asneeded, the stockpiled ore is further crushed and screened to about 50 millimeters (2 inches) in diameter. If the moisture content of the mined ore is greater than about 0.5 weight percent, the ore must be dried in a rotary

Gypsum
Gypsum rock is first mined or quarried, then crushed and ground to a fine powder. It then goes through a process called calcining where heat at 350 degrees is supplied to the gypsum powder which removes 3/4 th of the water molecules. Hemihydrate is the name of calcined gypsum which is then used in gypsum board, gypsum plaster, and other products.

Development and Mining. Overburden at the Bestwall operations is composed of 2 to 3 feet of soils underlain by 50 to 60 feet of glacial drift and gumbotil. The gypsum ranges from 20 to 27 feet in thickness and averages about 23 feet. The original stripping operations exposed the gypsum for a length of about 1,500 feet and a width of 75 feet.

overhead. This method of gypsum mining produces approximately 90,000 to 160,000 tons of ore a year. The largest gypsum quarry in the world, Gold Bond’s Milford, Nova Scotia operation, produces four and a half to five million tons of ore per year. The quarry process begins by first removing the earth over the deposit. Then gypsum ore is drilled

Processing and Drying Gypsum
Drying Gypsum. Drying is an essential in processing gypsum, whether mining or pelletizing. Gypsum dryers work as moisture control solutions. A rotary dryer is used to reduce the moisture content of the gypsum. Lifting flights inside the rotating drum shower the gypsum through a heated air stream, drying the material as it moves through the dryer.

Gypsum slurry mostly dewatered by a two-stage process: 1. Slurry is pre-thickened and partly classified by a set of hydro-cyclones in first step. Though not very common, static thickeners can be used alternatively. 2. Further dewatering and cake washing in second step.
Despite its abundance, and its seemingly simple makeup, however, relatively little is known about how the calcium sulfate mineral forms in nature. In a recent study, researchers have shed new light on the multi-stage process by which gypsum grows — and the findings could help develop more efficient ways to manufacture the material.
