South Africa, uranium was not extracted from the mil-led ore but dumped along with milling residues (tailings) onto sand dumps and later in 'slimes dams'.2 This changed in the 1950s when the cold war turned the radioactive metal into a resource of strategic signifi-cance. Supported by British and American scientists the
South Africa is among the top countries in the world regarding uranium reserves and accounted for a significant reserve base of an estimated 433,364 t of uranium, or around 7% of global proven reserves in 2010 (Mining Weekly, 2012). The country contributes over 45% to the total African uranium reserves.
Uranium mining and milling Overview The largest uranium ore deposits are found in Asia, Canada, Australia and Africa. Most of the world's uranium is mined in these countries. There are some uranium ore deposits in the UK but they are too small to be economic and so no commercial mining happens in this country.
However, in countries heavily engaged with uranium mining and milling, such as South Africa, Niger and Namibia, or in countries with expansive transportation facilities, like Djibouti and Tanzania, there is still a pressing need to establish requirements for the safe handling and transportation of radioactive material, and to equip regulators ...

First Uranium on Friday (Sep. 18) reported a fatality at its Ezulwini mine, in South Africa. First Uranium spokesperson Bob Tait said that there was an unexpected fall of ground in the area where underground crews were installing permanent supports in a stope on the 45 level of the Middle Elsburg Reef horizon, which is the uranium and gold ore ...
during the milling process. Additionally, uranium mill tailings keep on emitting dangerous radon gas for many years. The dangerous components of tailings are transported into the environment by wind, erosion or dam failures. During the process of uranium mining and milling, workers and the environment are exposed to dif-
Rössing Uranium Ltd was formed in 1970 (68.6% China National Uranium Corporation Limited – CNUC, 15% Iranian Foreign Investment Co., 10% Industrial Development Corporation of South Africa, 3% Namibian government). The company has mined the deposit from 1976 as a large-scale open pit in very hard rock.
CNNC, China-Africa Development Fund to develop uranium resources in Africa. China National Nuclear Corp, the nation's largest nuclear power plant builder, yesterday said that its subsidiary China Uranium Corp has signed an agreement with China-Africa Development Fund to jointly develop uranium resources in Africa, sources reported.
The country contributes over 45% to the total African uranium reserves. Despite hosting substantial uranium reserves, South Africa only produced about 579 t or 1.1% of the total global production in 2010 (Global Data, 2011).The Department of Energy, in 2008, reported that the 1 800 MWe Koeberg nuclear power plant contributes approximately 6% of the total …

This is particularly true for South Africa where uranium has been brought to surface for nearly 130 years by deep level gold mines. 28 According to WISE Uranium, South Africa currently hosts some 700 Mt of U mill tailings, accounting for 30% of the global total (2353 Mt, Fig. 8).

Moreover, South Africa's uranium industry has made monumental social and economic impacts on the country. While South Africa's progression in the nuclear world has bred positive benefits its lasting effects on their environment and the uranium miners could prove to do more harm than good in the future if more isn't done to regulate the industry ...
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, …
South Africa also possesses sizeable uranium reserves and has an extensive uranium mining industry, making the country one of the important producers of uranium in the world. The presence of this primary energy source in South Africa is a key element of security of energy supply nationally.

AngloGold Ltd is a key figure in uranium mining in Africa, owning an underground mine with an average annual output of 674 tonnes. Currently, the largest project for uranium mining in Africa is the Randfontein mine in Gauteng, also known as the Ezulwini project. Established in January 2007, the mine has an inferred uranium output of 83 969 tonnes.
Uranium ore concentrate (UOC) is a general term to describe the final product of uranium mining and milling, although the term "yellowcake" is still loosely used. In fact, UOC may be yellow (eg, ammonium diuranate, uranyl peroxide), dark green-black, grey (U 3 O 8),, and sometimes orange. Download : Download full-size image; Figure 6.8.
