uranium processing uranium processing leaching roasted uranium ores are leached of their uranium values by both acidic and alkaline aqueous solutions. for the successful operation of all leaching systems uranium must either be initially present in the more stable hexavalent state or be oxidized to that state in the leaching process. acid leaching is commonly performed by agitating anradioactive waste from uranium mining and milling 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 miners.
