Open pit mining. When uranium ore is found near the surface, generally less than 100 metres deep, it is typically extracted by open pit mining. Soil and waste rock is removed using conventional earth moving processes to access the ore. The walls of the pit are mined in a series of benches to prevent them from collapsing.

Open-Pit Mining: A Comprehensive Guide
Open-pit mining, or opencast mining, is a surface mining technique used for large-scale operations. It involves extracting minerals from a pit by removing waste rock and overburden. Commonly used for minerals like copper, gold, and iron ore, requires heavy equipment such as trucks and shovels to efficiently extract the ore.

Exploration, Mining, Milling and Processing of Uranium
Mining of metallic ores like uranium is carried out broadly by two methods based on locale. They are (i) surface mining and (ii) underground mining. Surface mining includes mechanical excavation methods such as open pit/open cast (strip mining) and aqueous methods such as placer and solution mining [19, 22]. Underground mining is …

Environmental and Health Consequences of Uranium Mining
Open-Pit Mining. In open-pit mining, rocks and soil are removed to expose and access the underlying uranium ore. These mines span hundreds to thousands of acres, as seen in Fig. 1. [4] For each ton of ore processed via open-pit mining, 40 tons of waste are generated, and dust and radon gas are released during this process.

Everything You Need to Know about How Uranium Is Mined
Open pit mining is a surface mining technique that is done by removing the top soil and rocks underneath to excavate the uranium ore. The debris is recovered and transported to the milling facilities. This type of mining is usually used if the uranium ores are located above shallow deposits. This form of mining is used for a high grade ore.
