Sampling and Characterization of Rock Material from Uranium Mining Waste Rocks for Study and Modeling of Release and Migration of Uranium

To study the effects of humic substances on the leaching and migration of uranium from uranium mining waste a natural rock material was sampled from a uranium rock pile situated in the mining region Schlema/Alberoda (Saxony, Germany). This report describes the sampling and characterization of the <1 mm grain size fraction of the rock material. The main focus is on the characterization of the sampled material with regard to its elemental and mineralogical composition and its amount of uranium that is accessible from the rock material by leaching processes.
