Uranium minerals identification

The aim of this study is to use mineralogical and geochemical tools for characterization of both types of uranium mineralization and possible identification of the U source(s). 

Appendices 1 and 2 have been prepared to assist in the mineral identification of uranium-bearing species. Appendix 1 contains the five strongest powder X-ray diffraction lines arranged in three-entry Hanawalt format. The data are mostly from the Powder diffraction and used with permission...

This appendix is intended to be a mini-search manual for the uranium minerals. Once the possible pattern matches are located using this abbreviated table, it will be necessary for the user to refer to the original data or the PDF for final confirmation of any identification.

World-wide activities focus on the remediation of radioactively contaminated sites. Part of such efforts were projects funded by the DFG (Deutsche Forschungsgemein-schaft) Characterization of colloidal particles in drainage systems of abandoned Sax-onian mines and Investigation of mechanisms of uranium(VI) sorption onto rock and mineral surfaces. Identification and modelling of sorbed surface species on a molecular level and funded by the EC Restoration Strategies for radioactively contaminated sites and their close surroimdings . One common aim was to deliver a more pro-... 

Identification of host minerals in bore-holes (i.e., measurement of uranium grade and type). 

A consideration of other elements associated with roll-front deposits improves the accuracy and confidence in locating favourable trends (Fig. 9). Sulphate concentration and conductivity increase toward the redox front and then decrease abruptly owing to precipitation of iron sulphide, followed by calcium carbonate. High values of bicarbonate and selenium also contribute to identification of the zone of uranium mobilization on the oxidized side of the front. Molybdenum concentrations are normally associated with sandstone deposits, but haloes in the groundwater may be to the side of or farther down-dip than the centre of the geochemical cell. Arsenic is most valuable for its regional halo around areas of mineralization.
