Uranium mining is the process of extraction of uranium ore from the ground. The worldwide production of uranium in 2019 amounted to 53,656 tonnes. Kazakhstan, Canada, and Australia were the top three producers and together account for 68% of world uranium production. Other important uranium producing countries in excess of 1,000 tonnes per year were Namibia, Niger, Russia, Uzbekistan and China. Uranium from mining is used almost entirely as fuel for nuclear power plants. get price

Uranium — How Is It Mined?

Open Pit MiningUnderground MiningMillingIn-Situ RecoverLinks to More InformationOpen pit mining, also known as strip mining, is the removal of surficial soils and uneconomic rock to get at the ore below. Ore grades are normally less than 0.5%. This is type of mining is only possible if the uranium ore is near the surface (normally less than 400 ft). The Jackpile Mine on Laguna Pueblo was once the world's largest open pit uranium mine.Waste rock or overburden (the material removed over the ore body) usuaSee more on geoinfo.nmt.edu

Underground Uranium Mining Underground Mines

Underground uranium mining is in principle no different from any other hard rock mining and other ores are often mined in association (e.g., copper, gold, silver). The uranium ore is extracted through mechanical means such as blasting, drilling, pneumatic drilling, picks and shovels, and then transported to get price

Radioactive Waste From Uranium Mining and Milling

Industries in the United States recover uranium from the Earth through mining or chemical extraction. Mining: When uranium is near the surface, miners dig the rock out of open pits. Open pit mining strips away the topsoil and rock that lie above the uranium ore. When uranium is found deep underground, miners must dig underground mines to reach it.get price

Uranium mining Energy Education

Mining. In general, uranium mining is relatively similar to other kinds of mining unless the ore is very high grade. In this case, special mining techniques are used to limit worker radiation exposure and to ensure the safety of the environment and general public. Depending on the deposit, uranium is mined in one of three ways: open pit, underground, or in situ recovery.get price

Uranium Mining Wyoming State Geological Survey

The main factors that determine whether to mine by open pit or underground are depth to the orebody and cost of production. Orebodies lying less than about 500 feet below the surface are typically surface mined as it is much cheaper than underground mining.
