The country mining the largest amount of uranium is Kazakhstan, which in 2015 produced 39% of the world's mining output. Canada was the next largest producer with a 22% share, followed by Australia with 9%. There are uranium mines on every inhabited continent.
Uranium is being mined in the DRC. The uranium for the nuclear bombs which were used to bomb Japan at the end of the Second World War came from this region, known then as the Belgian Congo. The mining occurs in the mineral rich province of Katanga, for example in Shinkolobwe,Mindigi, Kalongwe, Kasompi, Samboa and the Emmanuel Depot in Kolwezi. Major player is Gécamines, the state mining company.
The French conglomerate Areva has an undisclosed contract with Gecamines which is reportedly allows the company to mine unlimited amounts of uranium in the region
In Gabon, mining used to occur in Oklo, but the deposits are reported to be exhausted. In 1972, remains of a natural nuclear fission reactor were found at the Oklo deposits.
Uranium is produced at Kayelekera mine near Karonga. The mine owned and operated by Australian company, Paladin Energy. As of 2014, the mine is under 'care and maintenance' due to weak uranium prices.
Namibia produces uranium at Rossing deposit, where an igneous deposit is mined from one of the world's largest open pit mines. The mine is owned by a subsidiary of the Rio Tinto Group. The Langer Heinrich calcrete uranium deposit was discovered in 1973 and the open pit mine was officially opened in 2007. The Husab Uranium Project currently under development is expected to be completed towards the end of 2016. Its first drum of Uranium was produced in December 2016. As of 2013[update] the cost of uranium production in Namibia is among the highest of major producers due to the remote desert location of deposits.
