Cheonmasan is regarded as a uranium milling facility that is possibly also a site for uranium enrichment Most of the information regarding this facility is based on the testimony of North Korean defector Lee Choon Seon a former senior military official of the Korean People’s Army who defected to China in and was captured by the Chinese authoriti 2 Uranium mining is the process of extraction of uranium ore from the ground The worldwide production of uranium in amounted to 60 496 tonn Kazakhstan Canada and Australia are the top three producers and together account for 70 of world uranium production Other important uranium producing countries in excess of 1 000 tons per year

After uranium is extracted from rock the processes leave behind radioactive waste Uranium eventually decays to radium and then radon Open pit uranium milling and in situ mining sites do not pose a radon risk to the public or minersThe semi industrial plant at Kalna was constructed to separate ore extracted from Mt Stara Planina In it was operating with a capacity to process between 23 to 50 tons of ore per day During the s the plant conducted large scale uranium ore processing experiments to become familiar with the technologies and processes and to obtain necessary information to design industrial

Since natural uranium contains only 071 of fissile isotope 235 U and most of current power reactors require enriched uranium this natural uranium must be enrichedOnly uranium 235 is a fissile material ie is capable of undergoing nuclear fission only after capturing a thermal neutron but as it only accounts for 07 of the makeup of natural uranium it is not present in sufficient Uranium from Phosphates Updated May Rock phosphate deposits contain many million tonnes of uranium which may be extracted as a by product of making fertilisers Some 20 000 tonnes of uranium has already been obtained from these rock phosphate
