Gypsum is mined primarily where ancient salt seas existed. Gypsum is a naturally occurring salt/limestone, that is left behind when the water evaporates. Gypsum is mined near Las Vegas, Nevada and in western Michigan. The largest gypsum deposits in the world, in fact, are in Michigan.

Gypsum is primarily found in sedimentary rock formations around the world, with major deposits located in the United States, Canada, Mexico, and parts of Europe and Asia. It is typically extracted through surface mining methods, such as open-pit mining, where large amounts of overburden are removed to access the gypsum deposits. In some cases, underground mining techniques may also be used, depending on the depth and location of the gypsum. After extraction, the gypsum is crushed and processed for various industrial uses.
Plaster is commonly found in construction materials, such as plasterboards and plaster mixes used for walls and ceilings. It can also be found in art and sculpture materials for creating molds and casts. Natural gypsum, a mineral used to make plaster, is found in abundance in countries like the United States, China, and Iran.
