Iran Is Ranked Second After the United States in Production of Plaster of Paris (Gypsum Powder)

Gypsum deposits were formed millions of years ago when the salty waters of the oceans covered most of the earth’s surface. When the oceans retreated and were enclosed in land, swamps formed, and as this evaporation continued, the waters became saltier and saltier, and when these salts precipitated, they formed various compounds, one of which was gypsum. In fact, gypsum is one of the destructive sedimentary rocks and exists as a solution in seawater. When water evaporates in some parts of the sea, this substance (sedimentary rock) can no longer be soluble, so some of it is insoluble. Then, due to chemical activities, over the years, these salt deposits are combined with rotten plants and other minerals, and finally the result is the formation of layered rocks, one of which is alternately gypsum and the other layer It was limestone, this layer of rock, which is a kind of transparent sheet, turns into gypsum mines, which are of great geological value.

The world’s proven gypsum reserves are estimated at 3.3 billion tons. The amount of gypsum reserves by countries is given in the table below.

According to the table in terms of gypsum production, Iran has 10% of world production and is ranked second after the United States.

Gypsum reserves in Iran

Gypsum mines in Iran belong to the third geological period and their origin is sedimentary and are located on the ground. Iranian gypsum deposits have different qualities and with different geological conditions and can be found in almost all parts of the country, Main locations of gypsum Mines in Iran are found in center, west, north and south-western of country. Semnan, Qom, Yazd and Khorasan are main gypsum producers’ provinces. These areas are considered the most important location for gypsum phenomenon, due to the high thickness of gypsum extracts.

In Iran,  gypsum production is 13 million tons, which is 10% of the entire global gypsum output. Iran is second after the United States in production and supplies gypsum in the world. But because of very low-price human source and very reasonable Equipment in Iran, Also, Iran is located in the Middle East, and have land border with 7 countries ; Also Sea border with 7 Countries, it also has port in the Persian Gulf and Oman Sea which connects to international seaways. So, Iran has very strategic location and easy to access, There for we can supply gypsum with obvious more reasonable price than other countries, and we become to the most strategic and well-known manufacturers and Exporter of this great mineral product in the world.
