Open-pit and underground mining methods, both of which rely on physical extraction to obtain raw uranium ore, are commonly referred to as conventional mining methods. The reliance on chemical or other means to extract uranium are referred to as unconventional mining methods, even though they may have been used as extraction processes for decades.
Access to an open cut mine, often called an open cut or open pit, is via one or more ramps constructed at a suitable gradient and width to allow access by mining equipment. The design of the pit walls is strongly dependent on the geotechnical strength of the soil, sediment, or rock material.
Uranium Mining Although extensive ore reserves in the area will require underground mining methods, significant ore reserves were also found near the surface which can be mined by open pit methods. All ore presently being mined by Petrotomics Company is by open pit under contract to Plateau Construction Company of Rawlins, Wyoming.
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 ...
The mining method preferred for the Etango open pit will be a high tonnage (100Mtpa), low cost, traditional open pit truck and backhoe operation employing 550t diesel hydraulic excavators, off road 220t haul trucks and 203mm down the hole (DTH) hammer diesel drills.
