The First Discovery of a Large Sandstone‐type Uranium Deposit in Aeolian Depositional Environment
Acta Geologica Sinica - English Edition, 2020 deposits worldwide is mostly less than 700 m, and most of them occur in strata of fluvial facies (Adams et al., 1981; Jin et al., 2016; Hou et al., 2017). Only a few small uranium deposits have been reported in aeolian depositional environments (Isachsen

Column bioleaching of sandstone type uranium ore deposit
Pacific International Journal, 2019 Column bioleaching has been performed on sandstone-type uranium ore. The column is initially leached with H2SO4 to make the environment acidic and feasible for Thiobacillus ferroxidase bacteria growth. The column later injected with acid solution containing 6g/L H2SO4, iron source 1.5g/L (Fe3+ 0.75g/L, Fe2+ 0.75g/L) and bacteria.

In situ U-Pb Isotope Dating Techniques for Sandstone-type Uranium Deposits
Yankuang ceshi, 2020 BACKGROUND Uranium mineral dating has been difficult to ascertain in mineralization chronology. With the development of in situ U-Pb isotope dating technology, it is possible to directly date ore minerals (uranium minerals).
