Mining is done by blasting, loading and hauling from the open pit before the uranium-bearing rock is processed to produce uranium oxide. The open pit measures 3.5 km by 1.5 km and is 420m deep. The pit void is mined by a conventional truck-and-shovel operation, with mining being conducted in 15 m benches.

Open pit mining at Namibia's Husab project. Husab will be developed as an open-pit mining operation that uses a conventional truck and shovel …
Open-Pit mining requires creating a large pit in the ground extracting materials like silver from the earth. This includes removing a hilltop with rotary drills and explosives to expose the rocky materials beneath. Strip mining extracts thin layers of coal from near the surface. It starts with removing large strips of surface material, known as ...
The industry says new technologies will eliminate pollution from uranium mining, but its toxic legacy, particularly in the U.S. Southwest, leaves many wary of an incipient mining boom. ... much of our production was conventional open pit and underground," said Scott Melbye, president of Uranium Producers of America and CEO …
Lichtenberg open pit in Saxony, Germany, mined 1956–1976, now backfilled: 2000 m long, 1000 m wide, and up to 240 m deep (Wismut, 2014). Ranger Pit 3 in Australia, mined 1997–2012 and currently being backfilled: 1150 m long, 800 m wide, and up to 275 m deep (Wines et al., 2013). Open pits must also be protected from flooding …
