Dolomite 99% Micronized Made in Iran
Iranian dolomite, also known as dolomite rock or dolostone, is a naturally occurring mineral composed of calcium magnesium carbonate (CaMg(CO₃)₂). With a purity of 99% and a trigonal/hexagonal crystal structure, it is a versatile industrial mineral used in glass manufacturing, construction, ceramics, steel production, and polishing applications. Available in multiple grades including sugar, salt, pea, almond, walnut, lump, fine, coarse, and micronized forms, it offers high whiteness, chemical stability, and thermal resistance. Its unique composition makes it a valuable source of both calcium and magnesium.
The Supply Chain Department at Sahi Rasa Company supplies Iranian dolomite for export to Afghanistan, Iraq, the Kurdistan Region, Tajikistan, Uzbekistan, Armenia, Georgia, Turkey, and Syria. Whether for glass production, construction aggregates, ceramic bodies, or polishing compounds, the department ensures reliable supply, competitive pricing, and comprehensive logistics support.
1. Introduction to the Supply Chain Department at Sahi Rasa Company
The Supply Chain Department at Sahi Rasa Company has developed a specialized capability in the export of industrial minerals, and dolomite is a prime example of its expertise. The department understands that dolomite is not a single product but a family of products differentiated by particle size, chemical composition, and physical form. A glass manufacturer in Turkey may require a fine, low-iron dolomite with consistent chemistry; a construction company in Iraq may need a coarse aggregate for concrete; a steel plant in Uzbekistan may require a flux-grade dolomite with specific sizing. The department's ability to supply the right grade for the right application is what sets it apart.
The department's mineralogists and quality control specialists work closely with clients to understand their technical requirements and to select or blend dolomite to meet those requirements. The department also invests in processing equipment, including crushers, screens, and micronizers, to produce custom particle size distributions. This vertical integration ensures that the department can control quality from the quarry to the final bag.
For clients in Afghanistan, the Kurdistan Region, Iraq, Tajikistan, Uzbekistan, Armenia, Georgia, Turkey, and Syria, the Supply Chain Department at Sahi Rasa Company offers a reliable and flexible supply chain. The department's logistics team has experience in shipping to landlocked destinations, navigating border crossings, and coordinating with local partners to ensure smooth delivery.
2. Product Overview
Dolomite is a carbonate mineral composed of calcium magnesium carbonate (CaMg(CO₃)₂). It is closely related to calcite (CaCO₃) but contains magnesium in addition to calcium. Dolomite typically forms through the alteration of limestone by magnesium-rich fluids, a process known as dolomitization. Iranian dolomite deposits are known for their high purity and consistent chemistry, making them suitable for a wide range of industrial applications.
In the glass industry, dolomite is used as a source of calcium and magnesium oxides, which improve the chemical durability and melting characteristics of glass. In the construction industry, dolomite is used as an aggregate in concrete, asphalt, and road base. In the ceramics industry, it is used as a flux in glazes and bodies, lowering the melting point and improving thermal shock resistance. In the steel industry, dolomite is used as a flux in basic oxygen furnaces and electric arc furnaces, where it helps to remove impurities and protect the refractory lining. In the chemical industry, dolomite is a source of magnesium compounds, including magnesium oxide and magnesium sulfate. In agriculture, dolomite is used to neutralize soil acidity and supply magnesium and calcium nutrients.
The Supply Chain Department at Sahi Rasa Company offers dolomite in multiple grades, including raw lump, crushed aggregate, fine powder, and micronized powder. Each grade is produced to meet the specific requirements of the target application.
