Uranium is a naturally occurring radioactive element very widely distributed throughout the earth’s crust [ 1 ]. It is present in varied concentration in almost all types of rocks, natural water including sea water, and living organisms. The average concentration of uranium in the earth’s crust is about 2.76 ppm in rocks [ 2 ], less than 1

In strip mining, there are four major types, and they include surface mining, contour mining, placer mining, and In-situ mining. Surface mining is the most common form of strip mining and involves removing all the soil from a shallow layer of ground. In contrast, area mining involves removing soil from an entire region.

Conventional solution mining, also known as In Situ Leaching (ISL), refers to the artificial extraction of raw material, by pumping superheated water into deposits. The targeted minerals are dissolved, and the brine is pumped to the surface where it is cooled down, dried, and processed. The process is like heap leaching, where ore is extracted

Relatively large deposits that are quite close to surface and somewhat regular in shape are mined using open-pit mine methods (Figure 8.1.5 in Section 8.1). Creating a giant hole in the ground is generally cheaper than making an underground mine, but it is also less precise, so it is necessary to mine a lot of waste rock along with the ore, and that waste

Mining techniques can be divided into two common excavation types: surface mining and sub-surface (underground) mining. Today, surface mining is much more common, and produces, for example, 85% of minerals (excluding petroleum and natural gas) in the United States, including 98% of metallic ores.

Open-pit mining. Open-pit mining is the activity of removing the earth to access the mineral deposits and continuing to do it vertically in an open-pit. This method is best suited for mineral deposits that are close to the surface of the earth but are not accumulated in a horizontal manner. Open-pit mining often impacts a narrower surface area.
