Depending on how much the uranium is enriched it could be used for a nuclear power plant or if it is highly enriched to 93% then it is used to create a nuclear weapon. The Mining Process: There are three main methods of mining uranium, or any mineral for that matter. The first is open pit mining, also known as strip mining. It is a cheap mining ...

Uranium mining - Canadian Nuclear Association

The Olympic Dam is a huge mining centre located in South Australia, 560km north-west of Adelaide. Home to a major oxide copper gold deposit producing copper, uranium, gold and silver, the site hosts an underground mine and an integrated metallurgical processing plant. The project was opened in 1988 ...

5 Potential Human Health Effects of Uranium Mining ...

Nuclear reactor - Nuclear reactor - Uranium mining and processing: Uranium is extracted from ores whose uranium content is often less than 0.1 percent (one part per thousand). Most ore deposits occur at or near the surface; whether they are mined through open-pit or underground techniques depends on the depth of the deposit and its slope. The mined ore is crushed and the uranium chemically ...

what are underground uranium mine equipment

In the case of underground uranium mines, special precautions (consisting primarily of increased ventilation) are required to protect against airborne radiation exposure. In general, open pit mining is used where deposits are close to the surface and underground mining is used for deep deposits, typically greater than 100 metres deep.

Uranium Primer - Uranium Extraction Methods

Abstract: Underground mining technology advancements and automation have progressed significantly in the past 50 years; often the refinement of existing equipment, and the automation thereof, which in effect does the same thing. It's often about progressing mining methods that have incremental impacts, rather than stepchange benefits. Processing, both currently and traditionally, has been a ...

Based on the current understanding of uranium deposits in the Commonwealth of ia, extraction of uranium ore would use open-pit mining, or underground mining, or a combination of both ().These general terms incorporate a large variety of design possibilities—there are as many methods of mining uranium as there are orebody sizes, shapes, and mineral …

Uranium - Wikipedia

After locating uranium deposits and obtaining appropriate permits, a company will begin to mine. There are a few ways to extract uranium from the ground: open-pit mining, underground mining and in-situ recovery.. Mining methods depend on the type of deposit, whether it's suspended in water and the geography of the area.

Uranium mining - Wikipedia

Underground mining is the method of mining used when the ore being sought is well below the Earth's surface. An alternative to underground mining is open-cut mining, which is possible when the ore is close to the surface. All mines require ventilation and uranium mines are particularly well-ventilated to ensure exposure to radiation is minimised.
