The gold mine is located in the Kyzyl Kum Desert of Uzbekistan. The Kyzyl Kum area is made up of three main tectonic units, of which the oldest and major unit is the Besopan formation. The rocks are classified to be of Lower Palaeozoic carbonaceous and sulphidic clastic segments. The Muruntau deposit is located within the Beltau Kurama volcano plutonic belt. The belt stretches in arc shape for 1,300km to 1,350km from the Valeryanov zone of the Urals in the west to the Chatkal ridges in the east. The region has huge deposits of turquoise along with gold and arsenic deposits. Gold occurs in micro assemblages together with tellurides and selenotellurides of Bismuth mineral. The Tashkura region within the mine produces high quality phosphorite. The gold mine is estimated to hold more than 150Moz of resources.

The Muruntau gold mine employs open pit mining and heap leach processing. Gold mining is conducted using a truck and conveyor ore transportation system. The overburden is taken to the crushing and transhipping points using cyclic flow technology. The ore is transported using a steeply inclined SIC 270 conveyor, one rumble, two spreaders and two conveyer lines with a belt width of 2,000mm. The conveyor has a lifting height of 270m and an angle of 37°, which reduces the length of the ore mass transport by road by more than 3.5km. The conveyor can handle one million tonnes of ore per year with a hill climbing ability of approximately 37%. It has a capacity of transporting 50,000t per day. The rock is dumped directly to the surface using Rocky loader stacker 3500 dump hopper. The grinding loading complex comprises of grinding loading point and loading storing complex. The ore is crushed using LT160 crusher equipped with an advanced DNA automation system. It includes a four s...
Processing of ore at the Muruntau mine is performed at hydrometallurgical plant No. 2 , which was installed in 1969. The crushing and sorting complex processes the off balance ores from the open pit stockpiles to increase the ore feed reliability. Gold is extracted using the heap leaching method that helps in the efficient extraction of gold, even from low grade ores. Sorption and filter free process is used for extracting the gold. It also extracts refined sliver and palladium by products.
The mining fleet of Muruntau includes 200 BELAZ 75307 mining dump trucks of 220MT capacity. In addition, two Hitachi excavators with 19.4m³ bucket capacity and one Russian made ECG 15M excavator with 15m³ capacity are used.
Stage V Muruntau development project is the biggest of the 27 projects to be executed by Navoi between 2017 and 2026. The project is the part of the Uzbekistan Governments $3.63bn investment plan to modernise the countrys mining industry and increase the gold output. The stage V development is estimated to cost $733.9m for underground ore extraction and modernisation of the existing mining fleet, of which Navoi will invest $445.9m for the expansion while $228m will be funded by a loan from the Uzbekistan Fund for Reconstruction and Development. The project will uncover the reserves at the northern side of the open pit and will explore the reserves of the Besapantau, Chukurkuduk, Balpantau and Tamdybulak deposits. It will increase the volume of production and ore supply to HMP 2 to 50Mt/y. The project will employ Austrias Doppelmayer RopeCon®suspended conveyor system to transfer ore from the open pit to the surface. RopeCon provides a handling capacity of up to 25,000t/h.
Alteko was awarded the contract for installing the ore mining and transport complex at Muruntau mine. Novokramatorsk Machinery Plant provided the spare parts and components for the conveyor complex. Zarafshan Construction Administration was contracted to perform civil construction works for the mine. was awarded the contract to provide LT160 crusher for the mine. It also provided two MP1000 cone crushers, screens and VSI impact crushers as part of the contract. BELAZ was awarded the contract to supply 220MT mining dump trucks and BELAZ 76135 water sprinkler.
The cost of Navoi MMC is approximately 8 times less than foreign enterprises of this level At the present time, the book value of the Navoi Mining and Metallurgical Combine is estimated at $ 1.3 billion, while the market price of foreign enterprises at this level is $ 11 billion.
The total cost of the project was $10 million. By 2016, the company also intends to build and launch the Kayragach mine with a total capacity of 80,000 mt/y of ore at a cost of $30 million. The construction of new mines will increase gold production for the company by 25% 30%.
the capacity to process 35 Mt/yr of ore . In December 2016, the Almalyk GMK expanded the Kalmakyr Mine to be able to increase annual production by 4 Mt/yr of ore. The total cost of the project was $75.2 million, and it was financed by a $28 million loan from the FRRU, loans from
Muruntau Gold Mine, which is about 250 miles west of the capital in Uzbekistan, produced approximately 1,800,000 ounces of gold in 2010. Uzbekistan is one of the top ten gold producers in the world, whose deposits have an estimated value of $500 billion USD, with Navoi producing 80% of the countrys output.
Gold.The main gold producers of the country were two Government owned mining and metallurgical complexes the Almalyk GMK and the Navoi mining and metallurgical complex . The Muruntau deposit in the Central Qizilqum region had been mined by the Navoi GMK by open pit since 1969 and had relatively low extraction costs. The Navoi
Often forgotten on lists of major gold mining enterprises as they are state owned by Uzbekistan, Navoi Mining and Metallurgical Combine and Almalyk Mining and Metallurgical Complex are set to see their joint production exceed 5 Moz a year by 2026, an unprecedented figure, with Almalyks copper production also to reach 400,000 t/y.
