caption_attribution_description: English: The Erongo region is home to Rössing mine, the oldest and third-largest producer of uranium in the world. Situated about 70 kilometers (40 miles) northeast of the coastal city of Swakopmund, the mine is located near the ephemeral Khan River. The Advanced Land Imager (ALI) on NASA’s Earth Observing-1 (EO-1) satellite acquired this image of the mine and surrounding landscape on March 8, 2013. Roessing’s 400-meter (1,300-foot) deep pit and a large processing facility north of it are the dominant features in the bottom image. The pit taps into layers of metasedimentary rock that contain intrusions of a type of coarse-grained igneous rock called pegmatite. Pegmatite often contains rare minerals and forms when magma slowly cools and hardens beneath the surface. The mine sustains the small satellite town (population 7,600) of Arandis, which is visible near the top of the image. Roads and rail connect Arandis to Swakopmond, and there is a small airport south of Arandis. The dried channel of the Khan River is visible near the bottom of the image. While the surrounding landscape is largely devoid of vegetation, groundwater beneath the channel sustains some shrubs, trees, and grasses. The patches of green within and around the river channel in the top image are vegetation. Some Namibians and environmental groups have raised concerns that water samples from the Khan River channel showed elevated uranium levels. Uranium carried in wastewater from the mine may be reaching groundwater and increasing uranium levels near the river. However, a study led by Michael Schubert, a scientist from the Helmholtz Center for Environmental Research, found that uranium also occurs naturally in the channel sediments. His team found no evidence that water contaminated by the mine had seeped into the groundwater.
context_page_description: The Rössing Uranium Mine in Namibia is the longest-running and one of the largest open pit uranium mines in the world. It is located in the Namib Desert near the town of Arandis, 70 kilometres from the coastal town of Swakopmund. Discovered in 1928, the Rössing mine started operations in 1976. In 2005, it produced 3,711 tonnes of uranium oxide, becoming the fifth-largest uranium mine with 8 per cent of global output. Namibia is the world's fourth-largest exporter of uranium.
  In the apartheid era, the Rössing uranium mine was the focus of international criticism and protests by anti-apartheid and anti-nuclear groups, mainly in Europe. Reports that Rössing's uranium might be diverted to Iran, whose government owns 15% of the shares in the mine via its Iranian Foreign Investment Company, have been denied by the mine's management which maintains that the shareholding is entirely passive.
