Crystal gypsum in Semnan

Crystal gypsum, also known as gypsum stone, is a mineral substance that is naturally found in crystalline form in mines. This crystalline gypsum is also referred to as gypsum stone and is known as selenite in some sources. These crystalline stones are easily visible in the upper sections of open pit mines and foothills.

The appearance of this stone bears a close resemblance to mineral salt crystals. In the past, Crystals gypsum were not extracted extensively because they had limited applications and uses. Their primary use was as a support in mining operations. However, with advances in science and the presence of abundant calcium in these crystalline stones, gypsum gradually gained its true value and found applications in various industries. We will explore the various uses of gypsum crystal in detail in other sections of the article.

However, what makes this gypsum crystal valuable is its purity. The whiter, more crystalline, and overall purer the crystal, the higher its economic value. As you may know, in some mines in Semnan province, the world’s highest quality and purest crystals can be observed.

The extracted crystal gypsum from the mines in Semnan province can be observed in various forms such as tabular, sheet-like, and yellowish formations, among others. Pure crystal is completely colorless, and it is the various impurities that give it different colors. Organic matter, clay, and iron oxide can transform the color of the crystals into shades of gray, bluish-gray, pink, or yellow.

The extracted crystal gypsum is processed in the factory, often in the form of pieces mixed with impurities, mainly soil, and then reaches the end consumer. To process the crystal gypsum, it is first extracted from gypsum mines and transported to the factory. In the initial stage, the gypsum crystal is separated and graded for various purposes.

In nature, we introduced the formula for gypsum as calcium sulfate dehydrate. In the processing plants, the water molecule is removed from the extracted crystals through a heating process, reducing it to zero to two percent to make it suitable for pharmaceutical and medical uses. The product obtained from the calcination process is known as calcined gypsum. Some uses and applications of this crystalline gypsum require an additional autoclave process, where it is converted to alpha gypsum, suitable for medical, pharmaceutical, food, molding, sculpture, artificial stone, and other industries.

After adding water to the calcined powder, the recrystallization process occurs in reverse and imparts unique characteristics to this type of gypsum crystal. Some of these characteristics include high malleability, increased surface polish, high strength, fire resistance, moisture resistance, and more.

Crystal gypsum mines are scattered throughout the country, meaning this mineral is available in most regions of Iran. However, an important point is the difference in purity and transparency of the mineral in one region compared to others. Pure gypsum and crystal gypsum, due to their unique applications, often have export potential. Semnan gypsum, with various dimensions and particle sizes, is one of the country’s export products that is unparalleled worldwide and is exported with different purity percentages for various purposes.

The processed and cleaned crystal gypsum, which is extracted for export, is finely ground with high precision and loaded into jumbo bags with suitable particle size. It is then transported from Semnan to loading ports. The export of this product is carried out using large containers from ports to destinations worldwide.
