Localization conditions and ore mineralogy of the Ulziit hydrogenic uranium deposit, Mongolia

详细

Information on the speciation of uranium minerals in ore of the recently discovered Ulziit uranium deposit in Mongolia is given for the first time. The ore composition has been studied by analytical scanning electron microscopy and local laser luminescent spectroscopy. The ore formed as a result of epigenetic redox processes. Transition from permeable variegated fan sediments to poorly permeable gray-colored coalbearing lacustrine–boggy sediments is the main ore-controlling factor. High-tech uranium mining with borehole in-situ leaching is feasible.
