Where and how is uranium mined?
About two-thirds of the world’s production of uranium from mines is from Kazakhstan, Canada and Australia. An increasing amount of uranium, now over 60%, is produced by in situ leaching.
What is uranium mining?
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 uranium producers, respectively, and together account for 68% of world production.
How is uranium mined and refined?
In a conventional uranium mine and mill, uranium ore is extracted from the Earth, typically through deep underground shafts or shallow open pits. The ore is transported to a mill, where it is crushed and undergoes a chemical process to remove the uranium.
How is uranium mined safely?
A number of precautions are taken at a uranium mine to protect the health of workers: Dust is controlled, so as to minimise inhalation of gamma- or alpha-emitting minerals. In practice dust is the main source of radiation exposure in an open cut uranium mine and in the mill area.
What is mining and types of mining?
There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits.
Is mining uranium harmful?
Uranium mining has widespread effects, contaminating the environment with radioactive dust, radon gas, water-borne toxins, and increased levels of background radiation. Uranium mining is the first step in the generation of both nuclear power and nuclear weapons.
How is uranium extracted from water?
Improved extraction Scientists have long known that uranium dissolved in seawater combines chemically with oxygen to form uranyl ions with a positive charge. Extracting these uranyl ions involves dipping plastic fibers containing a compound called amidoxime into seawater.
What are the 4 steps of mining?
The mining industry operates through a sequence of stages: exploration, discovery, development, production and reclamation.
Where is uranium harvested?

What are the three processes of mining?
Open-pit, underwater, and underground mining. These are the three main methods of mining we use to extract our products from the ground. In this Digging Deeper article, we take a look at these different methods and provide a glimpse into what each involves.
