In-situ Micro-scale Pb Isotope Identification Characteristics of Metallogenic and Non-metallogenic Pyrites in Sandstone-type Uranium Deposits

open access: yesYankuang ceshi, 2022
BACKGROUND Sandstone-type uranium deposits contain a large number of pyrites of different shapes and stages. It is difficult to accurately discriminate the pyrite formed before, during or after the metallogenic period solely by observation of pyrite ...

Biogenic non-crystalline U (IV) revealed as major component in uranium ore deposits [PDF]

open access: yes, 2017
Historically, it is believed that crystalline uraninite, produced via the abiotic reduction of hexavalent uranium (U (VI)) is the dominant reduced U species formed in low-temperature uranium roll-front ore deposits.

Estimation of Filtration Properties of Host Rocks in Sandstone-Type Uranium Deposits Using Machine Learning Methods

open access: yesIEEE Access, 2022
The nuclear decay of uranium is one of the cleanest ways to meet the growing energy demand. The uranium needed for power plants is mainly extracted by two methods in roughly equal amounts: quarries (underground and open pit) and in-situ leaching (ISL ...

REE/trace element characteristics of sandstone-type uranium deposits in the Ordos Basin [PDF]

open access: yesChinese Journal of Geochemistry, 2006
The major elements, trace elements and REEs were analyzed on the samples collected from the sandstone-type uranium deposits in the Ordos Basin to constrain the mechanism of uranium enrichment. The total REE amount ranges from 36.7 to 701.8 μg/g and the REE distribution patterns of the sandstone-type uranium samples are characterized by LREE enrichment ...
