Gypsum Assets

Gypsum is mined throughout the world.


Gypsum is a common mineral that is a sulphate of calcium found in marine deposits where large amounts of seawater have evaporated. Gypsum can come in selenite, alabaster, satin spar and other types of stone, but it is typically processed and purified for use as fertilizer or as an additive for a variety of compounds. Gardeners throughout the world can use gypsum to modify their soil and make it more alkaline while enriching it with minerals.


North America


In the United States, the some of the major gypsum mines are found in Iowa, New York, Michigan and California. Iowa has one of the oldest mining productions, dating back to the 1850s, and even today, gypsum mining in places like Fort Dodge is very common. Many Canadian provinces also have gypsum mines, including British Columbia, Manitoba, Nova Scotia and Ontario. Canada supplies other countries, including Japan, with their primary gypsum imports.


Cyprus


In Europe, gypsum is also mined in many different locations, but one of the greatest deposits is located in the Mediterranean island of Cyprus. There are two primary Cyprus deposits, each running roughly parallel to the other and both dating back to the Miocene Age, when many gypsum deposits were created by retreating oceans. The Cyprus deposits include the well-mined Lupatza outcrop.


Asia


Some countries in Asia, like Russia, can mine their own gypsum from a variety of mines. Other countries like Japan have some production--in the Northern Honshu area--but must rely on outside vendors like Canada. In Southern Asia, West Pakistan produces a fair amount of gypsum in the Jhelum district, but the major produces for all of Asia is unquestionably India, which runs large-scale production and exports to most surrounding countries.


Australia


Australia has two levels of gypsum: older, inland deposits in dried-up lakes that are mined and newer deposits closer to the shoreline that are quarried. Lake MacDonnell and Spider Lake are two well-mined locations, with MacDonnell being the largest Australian gypsum mine. In addition, a large, undeveloped gypsum mine is located near Streaky Bay.
