Database location information: Russia
Diamonds were formed more than 300 million years ago. Kimberlite magma formed at a depth of 20-25 km. Magma gradually rose along faults in the earth's crust, and when the upper layers could no longer contain the pressure rocks, there was an explosion. The first such pipe was discovered in South Africa in the city of Kimberley - that’s where the name came from. In the mid-50s, the richest primary diamond deposits were discovered in Yakutia, where about 1,500 kimberlite pipes have been discovered to date. Engaged in the development of deposits in Yakutia Russian company ALROSA, which produces 99% of diamonds in the Russian Federation and more than a quarter in the world.
The city of Mirny is the diamond “capital” of Russia, located in Yakutia (Sakha) 1200 km away. from Yakutsk.
The Mir diamond-bearing pipe, discovered by geologists in the summer of 1955, gave its name to a workers’ settlement that grew up in the taiga and became a city 3.5 years later.
The population of the city is about 35 thousand people. About 80% of this population works at enterprises associated with the ALROSA group of companies.
Lenin Square is the city center.
Mirny Airport
Providing Mirny with food and consumer goods occurs in the following ways: aviation, shipping supplies (for the period while navigation is open on the Lena) and along the winter road.

The headquarters of Russia's largest diamond mining company, ALROSA, is located in Mirny.
The history of the company began with the Yakutalmaz trust, formed to develop the primary diamond deposits of Yakutia in the early 1950s.
The main deposit of Yakutalmaz was the Mir kimberlite pipe, discovered on June 13, 1955.
Then geologists sent an encrypted telegram to Moscow: “We have lit the pipe of peace. The tobacco is excellent."
The quarry is located in close proximity to Mirny.
From 1957 to 2001, $17 billion worth of diamonds were extracted from the deposit, and about 350 million m3 of rock were exported.
Over the years, the quarry expanded so much that dump trucks had to travel 8 km along a spiral road. from bottom to surface.
The quarry has a depth of 525 m and a diameter of 1.2 km, and is one of the largest in the world: the height of it could include the Ostankino TV tower.
The quarry was mothballed in June 2001 and since 2009, diamond ore has been mined underground at the Mir mine.
An aquifer passes through the area where the Mir pipe is located. Water is now entering the quarry and thus poses a threat to the mine underneath the quarry. Water must be continuously pumped out and directed into the faults that geologists have found in the earth's crust.
The volume of diamond production at the mine in 2013 amounted to more than 2 million carats.
Resources (including reserves) – more than 40 million tons of ore.
About 760 people work at the mine.
The company operates seven days a week. The mine operates on a three-shift basis, with shifts lasting 7 hours.
Surveyors who determine the direction of excavation through the ore body.
9 are used for excavation in the mine roadheaders(Sandvik MR 620 and MR360)
The combine is a machine with an executive body in the form of an arrow with a milling crown, which is equipped with cutting tools - teeth.
This Sandvik MR360 combine has 72 teeth made of hardened metal.
Since the teeth are subject to wear, they are inspected every shift and, if necessary, replaced with new ones.
To deliver ore from the combine to the ore pass, 8 loading and delivery vehicles (LODs) are used.
The main converter belt is 1200 meters long from the kimberlite pipe to the ore pass skip.
The average diamond content exceeds 3 carats per ton.
From this place to the bottom of the quarry is about 20 meters.
To prevent flooding of the underground mine, a pillar 20 meters thick was left between the bottom of the quarry and the mine workings.
A waterproof layer is also laid at the bottom of the quarry, which prevents water from penetrating into the mine.
The mine also has a water collection system: first, groundwater is collected in special settling tanks, then it is supplied to an elevation of -310 meters, from where it is pumped to the surface.
In total, the mine operates 10 pumps with a capacity of 180 to 400 cubic meters per hour.
Installation of the main tape
And this is underground work on another pipe - “International” (“Inter”).
It is located 16 km from Mirny. Open-pit diamond mining here began in 1971, and when the quarry reached 284 m by 1980, it was mothballed. It was with Inter that underground diamond mining began in Yakutia.
“International” is the company’s richest kimberlite pipe in terms of diamond content in ore - more than 8 carats per ton.
In addition, Inter diamonds are different high quality and are valued on the world market.
The depth of the mine is 1065 meters. The pipe has been explored to 1220 meters.
The length of all workings here is more than 40 km.
The combine beats ore with a working tool (cone cutter) with cutters installed on it.
Next comes loading into loading and delivery vehicles, which transport the ore to the ore passes ( mine workings designed for transporting ore from the working area to the transport horizon located below), then the trolleys transport it to the main ore pass, through which it is fed into the skip shaft and released to the surface.
1,500 tons of ore are mined at Inter per day. The volume of diamond production in 2013 amounted to more than 4.3 million carats.
On average, one ton of rock contains 8.53 carats of diamonds.
So, in terms of diamond content per ton of mined ore from Inter, there are 2 tons of ore from Mir, 4 tons from Aikhal, or 8 tons from Udachninsky.
Work at the mine is carried out day and night, seven days a week. There are only two holidays - New Year and Miner's Day.
Nyurbinskaya kimberlite pipe
The Nyurbinsky mining and processing plant was created in March 2000 for the development of deposits of the Nakyn ore field in the Nyurbinsky ulus of the Republic of Sakha (Yakutia) - the Nyurbinskaya and Botuobinskaya kimberlite pipes, as well as adjacent placers. Mining is carried out by open-pit and placer mining.
For the first time in the history of the merger between Yakutalmaz and Alrosa, Nyurbinsky GOK is using shift method- with the involvement of workers living in Mirny (320 km), in Nyurba (206 km) and in the village of Verkhnevilyuysk (235 km)
As of July 1, 2013, the depth of the Nyurbinsky quarry is 255 meters.
Open way the quarry will be mined up to 450 meters (up to -200 meters from sea level). There is potential to operate down to -320 meters.
To transport ore and overburden rocks, dump trucks with large and especially heavy load capacity are used - from 40 to 136 tons.
Caterpillar CAT-777D dump trucks with a lifting capacity of 88 tons are used in the quarry.
Nyurba Mining and Processing Plant has the highest growth rate of natural diamond production in AK ALROSA.
The volume of diamond production in 2013 amounted to 6.5 million carats.
The average diamond content in the ore is 4.25 carats per ton.
There are about 300-400 carats in the back of such a dump truck.
From a quarry or mine, ore is transported by dump trucks to a factory, where the minerals themselves are extracted from it.
The beneficiation of diamonds from the Mirny Mining and Processing Plant is carried out at factory No. 3, which in the 70s of the last century was the flagship of the country's diamond mining industry.
The capacity of the processing complex is 1,415 thousand ores per year.
Coarse crushing body and jaw crusher.
It grinds by rubbing the movable “cheek” against the stationary one. 6 thousand tons of raw materials pass through the crusher per day.
Medium crushing housing
Spiral classifiers
Designed for wet separation of solid material into sand (sediment, particle size up to 50 mm), and drain containing fine suspended particles.
Wet autogenous mill
Mill diameter - 7 meters
Rumble
The stones are sifted through a sieve, where they are divided into groups according to size.
Finely processed rock is sent to spiral classifiers (screw separators), where all raw materials are separated depending on their density.
The heavy fraction comes from the outer side, and the light fraction comes from the inner side.
Pneumatic flotation machine
Fine material, together with the addition of aqueous reagents, enters a pneumatic flotation machine, where crystals of small classes adhere to foam bubbles and are sent for finishing. The smallest diamonds are extracted using a pneumatic flotation machine - from 2 mm or less.
This is a film machine where reagents are used to create a layer to which small diamond crystals adhere.
X-ray luminescent separator
This separator uses the property of diamonds to glow in X-rays. The material, moving along the tray, is irradiated with X-rays. Once in the irradiation zone, the diamond begins to glow. After the flash, a special device detects the glow and sends a signal to the cutting device.
Central control panel of the processing plant.
The factory also has a finishing shop where diamonds are cleaned, scattered, hand-selected, sorted and packaged.
Diamond Sorting Center
All diamonds mined at the company’s fields in Yakutia are sent to the Sorting Center in Mirny. Here, diamonds are separated by size class, an initial assessment of raw materials from different deposits is carried out and its monitoring is carried out to plan the work of mining and processing plants.
There are no perfect crystals or two identical diamonds in nature, so their classification involves sorting.
16 sizes x 10 shapes x 5 qualities x 10 colors = 8000 positions.
Vibrating sieve screen. Its task is to divide small diamonds into size classes. For this purpose 4-8 sieves are used.
About 1,500 stones are placed into the device at a time.
The larger ones are handled by weighing machines. The largest diamonds are sorted by people.
The shape, quality and color of crystals are determined by appraisers using magnifying glasses and microscopes.
Dozens of diamonds pass through a specialist per hour, and if they are small, then the number goes into hundreds.
Each stone is looked at three times.
Manual diamond weighing
The weight of a diamond is determined in carats. The name "carat" comes from the seed of the carob tree, carat.
In ancient times, the carat seed served as a unit of measurement for the mass and volume of precious stones.
1 carat - 0.2 g (200 mg)
Stones weighing more than 50 carats are found several times a month.
The largest diamond on the planet, the Cullinan, weighs 621 grams and costs about 200 billion rubles.
The largest diamond among the Yakut ones is the “XXII Congress of the CPSU”, it weighs 342 carats (more than 68 grams).
In 2013, ALROSA Group enterprises produced more than 37 million carats of diamonds.
Of these, 40% goes for industrial purposes and 60% for jewelry.
After selection, the stones go to the cutting plant. There diamonds become diamonds.
Cutting losses range from 30 to 70% of the weight of the diamond.
As of 2013, the reserves of the ALROSA group amounted to 608 million carats, and the forecast reserves are about one third of the global total.
Thus, the company is provided with a mineral resource base for 30 years in advance.

ALROSA — Russian group diamond mining companies, occupying a leading position in the world in terms of diamond production (as of 2012). The name is derived from three words "(ALMAZY RUSSIA - SAKH)". The corporation is engaged in exploration, mining, processing and sale of rough diamonds. The main activities are concentrated in Yakutia, as well as in the Arkhangelsk region and Africa.
ALROSA produces 95% of all diamonds in Russia, the company’s share in global diamond production is 25%. The company has proven reserves sufficient to maintain the current level of production for at least 18-20 years. ALROSA's forecast reserves account for about one third of the world's diamond reserves.
Full name: Public Joint Stock Company Joint Stock Company ALROSA, short name: PJSC AK ALROSA. Headquarters are in Mirny (Yakutia) and Moscow.
The development of the diamond mining industry in the USSR began in 1954, when the Zarnitsa kimberlite pipe was discovered in Yakutia, the first primary diamond deposit on the territory of the Soviet Union. In 1955, the Mir and Udachnaya pipes were discovered; in total, 15 primary diamond deposits were discovered that year. In 1957, it was decided to begin mining operations at the placer and ore deposits of Yakutia, and the Yakutalmaz trust was founded in Mirny. In the same year, the first industrial diamonds were mined, and two years later the USSR began selling diamonds on the world market.
The main development of the industry was based on the development of the Mir kimberlite pipe and adjacent placers. During this period, the main mines were created, factories were built, and energy facilities were put into operation. In 1960, the Aikhal kimberlite pipe was discovered, and in 1969, the International pipe.
In 1963, the USSR concluded the first contracts for the sale of part of the diamonds to the international diamond mining corporation De Beers. In December 2008, by decision of the European Commission, in order to implement European antimonopoly legislation, the agreement between ALROSA and De Beers was terminated. Since 2009, ALROSA has been independently selling its products on the world market.
In the 1980s, the active development of the diamond mining industry continued based on deposits in the village of Aikhal, where the development of the Yubileiny pipe began, and in the city of Udachny. The main quarry of the Udachny plant is currently one of the largest open-pit mines in the world.
In accordance with the Decree of the President of the Russian Federation “On the formation of the joint-stock company Almazy Rossii - Sakha” dated February 19, 1992 No. 158C, a single joint-stock company ALROSA on the basis of Yakutalmaz enterprises, renamed in 1998 to AK ALROSA (CJSC). In 2011, AK ALROSA was transformed into an open joint-stock company. ALROSA shares entered free circulation on the stock market.
As of June 2013, ALROSA reserves and resources in accordance with the JORC code amounted to 971.7 million carats (of which proven - 664.8 million carats, probable - 308.2 million carats), which is 97% of the total Russian reserves of this raw material .
In 2012, ALROSA entered into a long-term contract with the Belgian company Laurelton Diamonds Inc., which purchases diamonds for the American jewelry company Tiffany & Co. Under the terms of the concluded three-year trade agreement at the first stage, Tiffany & Co. will be able to annually purchase approximately $60 million worth of rough diamonds.
In 2012, ALROSA Group enterprises produced 34.4 million carats of diamonds (approximately 6.88 tons). Diamond production in value terms amounted to $4.61 billion, sales of diamond products - $4.45 billion, polished diamonds - $160.6 million.
In the spring of 2013, Rosprirodnadzor of the Ministry of Natural Resources of the Russian Federation convicted AK ALROSA of unlicensed use of subsoil and unauthorized mining of diamonds in the territory of the Vodorazdelnye Pebble man-made deposit located in Yakutia (tailings from processing plant No. 5). According to government agency, the company illegally extracted over 1.7 million carats of diamonds from a deposit on state balance in 2010-2012.
According to representatives of AK ALROSA, the company was thus introducing new technologies for the cost-effective processing of mining waste - tailings. In addition, AK ALROSA coordinated this with Yakutnedra and Rosnedra, and also made all the necessary tax payments for this process. Later, a commission of the Ministry of Natural Resources, as part of an inspection of AK ALROSA, recognized the need to introduce new technologies for processing industrial waste and came to the conclusion that such a situation was not described by law.
In May 2013, ALROSA and the Sotheby’s auction house signed a memorandum of cooperation. Under its terms, ALROSA will be able to sell at Sotheby’s auctions large premium diamonds produced by a branch of the ALROSA Diamonds company, as well as jewelry with these diamonds. Stones offered for sale will be certified by the Gemological Institute of America (GIA).
On October 28, 2013, the company held an IPO, during which 16% of the company’s shares were sold (7% of shares were provided Russian Federation and the government of Yakutia, another 2% - quasi-treasury securities). More than 60% of the placement volume was bought by investors from the USA, 24% from Europe (20% from the UK), 14% was received by investors from Russia. Investment funds Oppenheimer Funds and Lazard each purchased 2%. During the IPO, ALROSA raised 41.3 billion rubles (about $1.3 billion).
In 2013, a program to exit the company from non-core assets. Thus, in April 2013, Alrosa Hotel CJSC was sold, and in March 2014, the sale of the Alrosa insurance company was announced.
In 2013, diamond production increased to 36.9 million carats, and diamond sales amounted to 38 million carats. In 2014, the company reduced production to 36.2 million carats.
