Uranium mining - Wikipedia

Uranium mining is the process of extraction of uranium ore from the ground The worldwide production of uranium in 2015 amounted to 60,496 tonnes Kazakhstan , Canada , and Australia are the top three producers and together account for 70% of world uranium productionUranium Mining Techniques | Investing News Network,Mining methods have been changing In 1990, 55 percent of world production came from underground mines, but this shrunk dramatically to 1999, with 33 percent at the time Since the year 2000, new Uranium mining in Australia - Wikipedia,Uranium mining in Australia has been highly political, particularly for the Australian Labor Party(ALP) at both state and federal level Development of projects has often been stymied by a succession of inquiries and the politicisation of the issuing of mining and export licences
