Biogeochemical aspects of uranium mineralization mining

 · 1. Introduction. Natural uranium (U) occurs as a mixture of three radioactive isotopes 238 U 235 U and 234 U. Only 235 U is fissionable and makes up about 0.7 of natural U while 238 U is overwhelmingly the most abundant at greater than 99 of the total mass of U. Prior to the 1940s U was predominantly used as a coloring agent and U-bearing ores were mined mainly for their radium (Ra
