Russia may face uranium raw materials shortage by 2030-2035, ministry says

Russia may face a shortage of uranium raw materials by 2030-2035, due to depletion of developed deposits, the Natural Resources Ministry said in a report on the state and use of mineral resources in Russia in 2020.
The ministry noted that although Russia possesses significant uranium reserves, most of the ores are of low quality. This makes it difficult or impossible to mine them in modern economic conditions.
According to the state report, as of January 1, 2021, the recoverable uranium reserves in the A+B+C1 categories total 327,100 tonnes, and in the C2 category - 383,500 tonnes. At the same time, the volume of production of uranium raw materials at the end of 2020 amounted to 2,897 tonnes, while the increase in uranium reserves due to geological exploration reached 281 tonnes.

Russia consolidates uranium production assets in new company

A founding treaty to set up the Uranium Mining Company was signed on November 2, 2006, at Russia's Federal Agency for Nuclear Power (Rosatom). TVEL will contribute three mining assets to the company: Hiagda, Priargunskoye Production Mining Chemical Association, and Dalur. Techsnabexport will contribute the Elkonskoye deposit in Yakutia and its share in the Russian-Kyrgyz-Kazakh JV Zarechnoye. In addition, the company may include Kazakhstan's Yuzhnoye Zarechnoye and Budyonnovskoye deposits, and set up JV Akbastau to develop them. Additionally, Techsnabexport is continuing talks to start up a uranium operation in Uzbekistan.
The new mining company will do several things: follow up exploration and exploitation of deposits located in Russia and development of the country's raw materials, including geological prospecting. The company is also expected to set up joint ventures to produce uranium in and outside the country, and import uranium. In addition, it will channel Russian and foreign investments into uranium production. The new company may form a partnership with western investors to develop uranium deposits.

Capacity increase of calcination plant at Krasnokamensk for processing of yellow cake from Khiagda ISL mine

In the hydrometallurgical plant of Priargunskoe Mining and Chemical Association (PJSC PIMCU) in Zabaikalskiy region a new line for deoxidation of ammonium polyuranates was commissioned. Additional equipment will make it possible to process here the entire volume of the final product of JSC Khiagda that produces uranium in the territory of the Republic of Buryatia.
"The transportation of final products for additional processing to Krasnokamensk is much more profitable than the construction of an additional redistribution line at our industrial site, in the conditions of permafrost. The enterprises are in geographical proximity to each other, so the logistics costs are quite small compared with the economic effect for the entire division," adds Andrey Gladyshev, General Director of JSC Khiagda.
The project for the additional processing of ammonium polyuranate of JSC Khiagda at PJSC PIMCU has been under implementation since 2017. The new deoxidation unit will double the processing capacity. (ARMZ Dec. 24, 2019)

Krasnokamensk mine starts industrial-size processing of subeconomic ore dumps for residual uranium

Over 48 years of the company's activities around 7 mln. tons of ore mass with extremely low uranium content have been accumulated on our industrial site. Industrial processing of off-balance and poor balance spoil heaps became possible after acquisition and launch of the KLEEMANN Mobile Sorting Unit. Annually the unit will process up to 375,000 tons of off-balance spoil heaps.
"The equipment divides the ore mass into merchantable ore and waste rock. Then the heap leaching method is used to extract uranium from the ore. The waste rock that remains after the sorting will be crushed into gravel, which then will be used for the technological needs of the enterprise," said Alexander Morozov, head of the CR&DL.
From 50 to 63 tons of uranium will be produced annually from the off-balance spoil heaps by the heap leaching method. (Atomredmetzoloto Nov. 14, 2016)

Two uranium mines at Krasnokamensk to resume operations after implementation of cost reductions and use of acid block in situ leaching

Priargunsky Industrial Mining and Chemical Union (JSC PIMCU, a part of the control loop of ARMZ Uranium Holding Co / JSC Atomredmetzoloto) has commenced preparations to resume operations at two uranium mines - Mine No. 2 and Mine No. 4.
Operations at Mine No. 2 were suspended on April 1, 2014 due to the decline in world uranium prices and, as a consequence, economic inefficiency. According to PIMCU Geological Department, uranium reserves of Mine No. 2 total 11,000 tons. "Presently technological measures that allow to minimize costs have been developed and will be implemented," - explains Sergei Shurigin, director general of PIMCU. Production is to be resumed in February 2015.
Mine No. 4 was closed due to depletion of reserves minable by conventional mining method. The remaining reserves total about 6,000 tons of uranium, and are to be mined using less costly method - block in-situ leaching. The technology involves acidification of ore directly in ore blocks. This eliminates the need to transport ore to the surface, thus significantly reducing the costs. Mining operations are expected to start in March 2015.
Currently JSC PIMCU is mining uranium by conventional method at Mine No. 1 and Mine No. 8, as well as by heap leaching of off-balance wastes. (Atomredmetzoloto Nov. 17, 2014)

Krasnokamensk mine starts processing of subeconomic ore dumps for residual uranium

The project for ore-sorting of non-commercial dumps was launched in August 2013, when an ore-sorting complex was installed, including a mobile screening plant and an X-Ray magnetic separator. This equipment separates rock bulk into saleable ore and mining waste. "Ore-sorting allowed us to obtain more than 50,000 tons of saleable ore, from which 10 tons of uranium was eventually extracted", says Alexander Morozov, Head of the JSC PIMCU Central R&D Laboratory.
It was decided to purchase the second ore-sorting complex. Once it is put into operation, production volume will increase up to 300,000 tons of saleable rock bulk per annum. (Atomredmetzoloto Aug. 4, 2014)

Russia's flagship Krasnokamensk uranium mine unprofitable due to low uranium price and decreasing productivity - cost reductions planned

"Taking into consideration the current situation on the uranium market, characterized by overproduction of this metal and drop in prices, diversification seems to be of particular importance for JSC PIMCU. Today, the enterprise is unprofitable, with production costs growing and the level of product output per person decreasing. On the Briefing Day, traditionally held for the Industrial Union's employees and the Krasnokamensk city residents, JSC Atomredmetzoloto Director General told them about decisions that had been made. He said that for JSC PIMCU to reach break-even operation it is necessary to reduce expenses by 3 billion rubles [US$ 83 million] in 2014 and 2015, i.e. by 1.5 billion rubles [US$ 42 million] annually."
