Sodium sulfate: Sodium sulfuric acid salt
Chemical name: sodium sulfate
Chemical formula: Na2SO4
Solubility in water: Soluble in water
Appearance: white powder
Grade: Industrial and food
Types of sodium sulfate
If sodium sulfate in its natural form is a hydrated salt, it is called Mirabilite.
Hydrous sodium sulfate or mirabilite is more common in nature.
Anhydrous sodium sulfate
The dry type is known as Thenardite
Crystal white with the formula Na2SO4.
Mineral: Sodium sulfate is found as a mineral in nature or is produced as a by-product through some industrial processes. Sodium sulfate is the main mineral in brines and the main source of sulfates is natural brines or salt lakes and is considered as a coastal sedimentary element.
Country Rock Age: Quaternary (Qt3, Qc)
The Qc Formation consists of vast areas composed only of fine-grained elements, mainly clay and large amounts of salts, which have been released by running water as their energy decreases. The Qt3 Formation is a low-altitude alluvial fan in the Quaternary period.
Structural geology: South Alborz zone
The Alborz Mountains form the east-west mountain range in northern Iran and south of the Caspian Sea. The Alborz Mountain range is part of the northern part of the Alpine-Himalayan orogeny in western Asia, which is bounded on the north by the Caspian Basin and on the south by the central plateau of Iran.
Sodium sulfate ore is the main mineral in brines and the main source of sulfates is natural brines or salt lakes and is considered as a coastal sedimentary element.
Type of sodium sulfate: Sodium sulfate is aqueous (Mirabilite). In the hot summer season, Mirabilite turns into thenardite due to heat. In the southern part of the mine, sodium sulfate is formed in the form of large salt plates with sodium sulfate. The mineral is in the form of thin layers with a thickness of 5 to 10 cm in the plain with a low slope to the southeast.
The hardness of this mineral is 1.5 to 2% and its specific gravity is 1.4%.
