Uranium pollution of South African streams – An overview ...

During more than a century of gold mining in South Africa large amounts of tailings were produced, which now cover vast areas in densely populated regions. These dumps contain elevated levels of uranium and other toxic heavy metals associated with gold in the mined ore. Large-scale extraction of uranium from auriferous ore only took place during the cold war,

Integrated Annual Report 2015 Sibanye Gold

The uranium ore is first treated for uranium and then subsequently to recover gold. Production of uranium as a by-product enables Cooke’s gold Mineral Resources to be optimised. Revenue from the sale of uranium is offset against gold production costs, thereby allowing lower-grade gold resources to be mined profitably.
