Mining and milling. Markus H.A. Piro, Ksenia Lipkina, in Advances in Nuclear Fuel Chemistry, 2020 8.2.3.1 Open pit mining. Open pit mining refers to mining directly on the ground surface, thereby producing an open pit. This method is practical and cost-effective when the uranium ore is located near the surface (e.g., within 100 m). Underground …

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.
