Basic chemical and physical properties of magnesite and brucite. Magnesite - a talisman with an ancient history

Climax

Magnesite is a common mineral, anhydrous magnesium carbonate from the calcite group. Included in the solid solution with siderite (FeCO3) and gaspeite (NiCO3). Synonym: magnesian spar. The flame does not color. It dissolves in acids only when heated. A drop of HCl does not boil in the cold. It dissolves in hot acids.

Chem. composition: magnesium oxide (MgO) 47.6%, carbon dioxide (CO 2) 52.4%. Impurities of iron, manganese, calcium.

Varieties of the mineral:
Breunnerite is a type of ferruginous magnesite with a percentage of Mg:Fe2+ atoms from 90:10 to 70:30.
Gelmagnesite, colloidal magnesite (gelmagnesite, kolloid-magnesite) is an amorphous (devoid of a crystalline structure) variety of magnesite.
Ferrous magnesite (ferroan magnesite), (Mg,Fe)CO3 is a ferruginous variety of brown magnesite.
Mesitine spar is a ferruginous variety of magnesite with an atom ratio of Mg:Fe2+ from 70:30 to 50:50.
Nickel magnesite, hoshiite (nickeloan magnesite, hoshiite) - a variety of magnesite enriched with nickel.

The crystal structure is the same as that of calcite.
Compared to calcite, magnesite is much less common in nature, but sometimes occurs in large continuous masses of industrial interest.

Some of these accumulations are formed by hydrothermal means. First of all, these include rather large deposits of crystalline-granular masses of magnesite, spatially associated with dolomites and dolomitic limestones. As geological studies show, these deposits are formed in a metasomatic way (among the deposits, it was sometimes possible to establish relics of limestone fauna). It is assumed that magnesia could be leached and deposited in the form of magnesite by hot alkaline solutions of dolomitized strata of sedimentary origin. Typical hydrothermal minerals rarely occur in the paragenesis with magnesite.
Accumulations of cryptocrystalline ("amorphous") magnesite also arise during the processes of weathering of massifs of ultrabasic rocks, especially in those cases when a thick crust of destruction products is formed during intense weathering. In the process of oxidation and hydrolysis, magnesium silicates undergo complete destruction under the influence of surface water and atmospheric carbon dioxide. The sparingly soluble iron hydroxides that arise in this case accumulate near the surface. Magnesium in the form of bicarbonate, as well as released silica (in the form of sols) sink into the lower horizons of the weathering crust. Magnesite, often enriched in opal and dolomite, in the form of veinlets and accumulations of sinter forms is deposited in highly leached fissured porous serpentinites in the zone of stagnant groundwater.
Finally, finds of magnesite with hydromagnesite (5MgO.4CO2.5H2O), mostly of mineralogical significance, are observed among sedimentary saline deposits. The formation of magnesium carbonates is associated with the reaction of the exchange decomposition of magnesium sulfate with Na2CO3.
Place of Birth

The well-known Satka deposit of crystalline magnesite of hydrothermal origin is located on the western slope of the Southern Urals (50 km southwest of the city of Zlatoust). Large magnesite deposits were formed here metasomatically among the dolomite sedimentary sequence of the Precambrian age. Similar deposits are known in the Far East, in South Manchuria, Korea, Czechoslovakia, Austria (Weitsch, in the Alps, south of Vienna) and in other places. It is formed together with talc during metamorphism (Shabrovskoye deposit, Middle Urals) and weathering of ultrabasic rocks(Island of Euboea in the Aegean Sea, Greece.
The deposits formed in the ancient weathering crust of ultramafic rocks include Khalilovskoye (South Ural) and the deposits of the island of Euboea in the Aegean Sea, Greece.
Sedimentary magnesite is deposited in lakes and lagoons, interbedded with dolomite or mixed with anhydrite. The largest deposits are in the strata of lagoon-marine dolomites: magnesite layers up to 500 m thick and tens of kilometers long (Satka in the Urals, deposits of the Liaodong Peninsula, China).
Practical value

It is an ore of magnesium and its salts; used for the production of refractories and binders, in the chemical industry; used for the production of refractory bricks. In the extraction of magnesite, mechanical (manual and with the use of photocell and laser devices) is used only to a limited extent, sometimes also flotation and electromagnetic enrichment. At a temperature of 750-1000 ° C, a powdered chemically active, so-called, is obtained from magnesite. caustic, magnesia, from which CO2 has not yet been completely removed. At 1500-2000°C, refractory magnesia is obtained, which consists mainly of periclase (MgO) crystals with a melting point of about 2800°C. At elevated temperatures (up to 3000°C), extra pure fused periclase is obtained in electric furnaces.
The most massive product of magnesite processing - refractory magnesia - is used mainly in metallurgy. Caustic magnesia is used in chemical processing processes (weakly alkaline reagent, catalyst, etc.), as a fertilizer, for feeding livestock, in special cements, in the production of cellulose for gas purification, in the manufacture of filters, etc., for the production of viscose, synthetic rubbers , paints (refractory filler), sugar and sweets, in winemaking, glassmaking, ceramics (fluxes), electric heating rods, water and gas cleaning, uranium processing, as an anti-corrosion additive to petroleum fuels, etc.

V jewelry industry magnesite is widely used. This stone lends itself to coloring, so the most various decorations. Magnesite is painted under red coral, lapis lazuli, turquoise.

The treasury of the planet is full of enchanting beauty with gems. Magnesite is a natural stone, which is the least noticeable, if evaluated at first glance. However, its healing value is superior to other crystals. Due to the wide range of uses, it is considered the most sought after, unlike all known mineral rocks.

History and origins

The ancient origin of magnesite is a historical fact. Its healing, magical, and also refractory properties were known in antiquity, people could use the mineral for its intended purpose.

The first fossil was discovered in Magnasia, which is located in Greece. One of the largest mines was discovered there. The breed contained in them aroused interest among local population. They tried to burn the ore, as a result of which it turned out that it can withstand high temperatures. Since then, magnesite has been used as a refractory material.

Its deposits are found in the form of large layers, thanks to which it has found application in some industrial sectors. In the largest deposits, at medium and shallow depths, such masses are formed as a result of hydrothermal processes. Crystal-granular formations of the mineral were exposed to hot alkaline solutions, resulting in the formation of ore.

Hydrothermal crystals of value are found in mineral formations adjacent to magnesite. Cryptocrystalline magnesite is formed by the weathering of rocks.


During the chemical reaction of water, air and mineral mass, magnesia silicates are destroyed, which contributes to the precipitation of magnesite in pores and cracks in which groundwater stagnates. In a mineral formed in this way, there are impurities and, as indicated by veins.

Magnesite with hydromagnesite is found in sedimentary rocks of salt-bearing deposits; such fossils are of interest for jewelry production.

Deposits / manifestations

Large crystals of magnesite are found in the province of Carinthia in Austria and near the city of Brumado, Bahia in Brazil; magnetite finds are also known on the territory of the Magnesia region in Greece; on the Piedmont Plateau Italy; Canada at the Del Oro field, in the province of Ontario; China in the province of Laonin; Norway; USA at a large field in the Gabbs area, Nevada, at large fields in California, in the state of Washington. V Russia magnesite is found at the Onot deposit (Irkutsk region).

Application

Magnesite is an ore of magnesium, metallic magnesium and its salts are obtained, it is used in the manufacture of alloys necessary in medical production and construction. In metallurgy, fired crystalline magnesite is used for the manufacture of refractory bricks that can withstand temperatures up to 3000°C. The second area of ​​application of burnt magnesite is the manufacture of cement used in the abrasive industry and construction. Magnesite is used for the production of electrical insulators, in paper, sugar, rubber and other types of production. Magnesite mineral raw materials are also widely used in the chemical industry and in the production of fertilizers.

Magnesite is natural mineral containing magnesium carbonate. The stone is most often gray or white, sometimes it can have a brown, greenish, yellow tint. Attracts a glassy, ​​matte sheen of magnesite. Stone crystals have different grain sizes and increased density. The mineral is very brittle and sensitive to high temperatures, making it difficult to process. Why is magnesite useful? What is the purpose of the stone?

Description of magnesite

The composition of the stone contains magnesium, calcium, iron impurities, carbon dioxide. The main component of magnesite is magnesium oxide. The mineral was named after the location. For the first time they started talking about the stone in ancient greece. Magnesite is mined in Mexico, Russia, USA, Australia, China, India, Austria. The mineral is hard to confuse with others, it has a bright yellow color and is actively used for jewelry purposes. In India, a transparent type of magnesite is mined.

Magnesite is widely used in agriculture and industry. It is especially actively used in the manufacture of cellulose, filters for water purification. It has been proven that magnesite helps to quickly disinfect water, rid it of sediment, heavy metals. Magnesite is used in the petrochemical, refractory industry.
