Mining Uranium Ore At Percent
Most of the uranium ore deposits at present supporting these mines have average grades in excess of 010 of uranium that is greater than 1000 parts per million In the first phase of uranium mining to the 1960s this would have been seen as a respectable grade but today some Canadian mines have huge amounts of ore up to 20 U average grade
