Uranium mining
As with other types of hard rock mining there are several methods of extraction. In 2016, the percentage of the mined uranium produced by each mining method was: in-situ leach (49.7 percent), underground mining (30.8 percent), open pit (12.9 percent), heap leaching (0.4 percent), co-product/by-product (6.1%). The remaining 0,1% was derived as miscellaneous recovery. Uranium resources can be extracted from the ground in three ways: open pit, underground, and in-situ leach (ISL). Open Pit Mining.

What is Uranium? IAEA International Atomic Energy Agency
In the 21st century this method has been gradually replaced by “in-situ leaching”. While only 16 per cent of uranium were produced via this technique in 2000, in-situ leaching is currently the most common method of uranium mining. In 2020, around 58 per cent of uranium worldwide was mined using this method.Even when the signature is weak, improved analytical techniques with lower detection limits for uranium, boron and lead can be used to detect alteration.

Uranium mining leading uranium producer Orano
Mining activities are Orano’s core business. With uranium mines in operation in Canada, Kazakhstan and Niger, Orano is one of the world’s leading producers of uranium, with competitive production costs and extraction techniques at the cutting edge of innovation.Uranium mining companies use detailed mapping techniques to locate the uranium and then design the wells to fit the specifications of the site. At its most basic, in-situ mining is a process by which the miners drill a well straight down to Wyoming Mining Association: Uranium Mining

Uranium mining Energy Education
If the quality and amount of uranium is sufficient, underground mines will be established.The first step is to dig large vertical underground shafts to the depths of the ore. Once this is done, horizontal tunnels, ramps, and chambers are built, allowing for the mining of uranium. There are different techniques to obtain the uranium at thisThe solution dissolves the uranium and then these uranium-rich fluids are pumped to the surface where the metal is extracted. This means that conventional extractive mining techniques (open-cut or underground mining) are not required. Significant uranium mining has not occurred in Queensland since 1982 due to a ban by the Uranium and thorium Geoscience Australia

Solution (in situ leach) mining of uranium: an overview OSTI.GOV
One of these new methods is in-situ solution mining, a relatively old mining technique that only recently has been successfully applied to the mining of uranium deposits. The technique involves: (1) drilling a series of injection and recovery wells into a uranium-ore body; (2) injection of a weak alkaline or acid-leach solution and an oxidizerEarly uranium mining techniques and poor health and safety standards, coupled with rudimentary knowledge about radiation exposure, made working in the mines unsafe. This meant there would also be a tremendous human cost, both in Africa and the United States. Uranium Mining in the Belgian Congo. Shinkolobwe MineUranium Mining Nuclear Museum

Nuclear reactor Uranium Mining, Processing Britannica
Nuclear reactor Uranium Mining, 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 Extractingg uranium from its ores by D.C. Seidel* The development of the uranium mining and ore processing industry is unique.

In this paper, mining techniques of uranium were investigated. Basically three type of mining techniques are applied. Basic mining techniques are underground mining, open pit or surface mining and in-situ leaching mining methods. Each of them has several advantages and disadvantages to the other.
