Magnesite exports from Iran: We export raw magnesite stones and lumps as well as processed magnesite containing different grades of Magnesium Carbonate and Magnesium Oxide from Iran.

Magnesium oxide with chemical formula MgO is a moisture-absorbing white material known as a magnesium source.

Magnesium oxide is produced by calcination of magnesium carbonate or magnesium hydroxide or magnesium chloride processing by lime and heat.

Magnesium oxide or magnesite is widely used in the refractory products industry, groundwater remediation, water treatment, drinking water treatment and more. In addition, magnesium oxide is used for buffering properties in acidic environments and its ability to stabilize insoluble heavy metals are among the reasons for its wide application in various industries. About 75% of the magnesium oxide produced in the United States was used in the refractory industry in the year 2004, and the remaining 25% was used in industries such as agriculture, chemicals, construction, and other industries.

Iran’s magnesium deposits are produced to varying degrees mainly in eastern Iran. More than 70 percent of Iran’s magnesium is produced in South Khorasan in the Sarbisheh and Nehbandan counties and the rest is mainly supplied by mines in Sistan and Baluchistan province. The eastern magnesium deposits of Iran are formed along the Nehbandan fault and on or near the ophiolitic units. These deposits occur in veins, streaks, and layers.

Iran’s magnesium mines are capable of producing 300,000 magnesiums of different purity annually, more than 70% of which is used in the refractory industry.

Magnesite with the formula MgCO3 is known to be the most important and valuable mineral of magnesium. The mineral crystallizes as a member of the carbonate group in the trigonal system, the Scalenoidric class. It is rarely seen in the crystalline form and is rhombohedral if formed. It is commonly found with minerals Hondite, Hydromannite and Chromite. Its chemical composition is 47.8% magnesium oxide and 52.2% carbon dioxide. It may substitute for some magnesium, which, when iron is increased, its chemical composition shifts to siderite. Some calcium and manganese may also be found in its composition. Its structure is similar to calcite. Magnesite minerals are white, gray, yellow with white soil and glassy to matte, and their specific gravity is 2.9 to 3.1 g / cm3 with a hardness of 3.5 to 4.5 at the scale of the mousse. Of the facial characteristics of the shell is the failure of the shell and the ramboeder. It appears with translucent glass to translucent glass.

Worldwide storage and production of magnesium:

The world’s definite reserves of magnesium are 5.2 and its base reserves are 4.3 billion tons. Worldwide production of magnesium is about 20 million tonnes, of which the largest share was in the newly independent countries of the Soviet Union, China, North Korea, the Czech Republic and Slovakia. The main producing countries are Australia, Greece, Turkey, Spain, Brazil, Yugoslavia, India and Canada.

Magnesium Mining Products:

Magnesium oxide

Iran Chemistry is one of the largest magnesium oxide producers and suppliers in the country with one of the country’s magnesium oxide mines and baking furnaces. The appearance of this composition is white powder.

Magnesium nitrate

This fertilizer is completely dry and soluble in water without any residue. This fertilizer can be used in all irrigation systems and is free of sulfate, chlorine and sodium.

Magnesium Sulphate

Magnesium sulfate is a mineral compound whose chemical composition is magnesium, sulfur and oxygen. Its chemical formula is MgSO4. Magnesium sulfate is easily soluble in water. Its appearance is colorless and odorless.

Magnesium carbonate

Magnesium carbonate in calves prevents the formation of tetanus deformity, especially herbaceous tetanus, avoids calcium and phosphorus imbalance in poultry blood, coma and seizures, as well as bone softening and torsion, and also reduces growth and decreases it. Egg production is also deficient in the shape of the egg shell.

Potassium nitrate

Sodium or potassium nitrate is a chemical compound, potassium nitrate is an almost strong oxidizer. Potassium nitrate is used in the manufacture of products such as gunpowder because it absorbs water. Dandruff gets moist and loses its moisture when exposed to the open air.

Potassium sulfate

Potassium sulfate is an inorganic chemical compound with white powder and water soluble K2SO4 formula. The major use of potassium sulfate or potassium sulfate in agriculture is as fertilizer to provide potassium and sulfur in the soil.
