Control of tectonic uplift and denudation on uranium mineralization in the eastern Junggar Basin

Meitan xuebao, 2023
There is a close dynamic coupling relationship between tectonic and mineralization. Long-term research and observation have found that the formation and location of sandstone-type uranium deposits are obviously controlled by the formation of target layer

Determination of Trace Rhenium in Sandstone-type Uranium Deposits by Inductively Coupled Plasma-Mass Spectrometry with Magnesium Oxide Sintering

Yankuang ceshi, 2016
The average content of uranium in sandstone-type uranium deposits is 635 μg/g, whereas the content of rhenium is 0.3-1.9 μg/g. Because of low rhenium content, now precise determination of low Re in high U ores remains unresolved.

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.

Genesis of green sandstone/mudstone from Middle Jurassic Zhiluo Formation in the Dongsheng Uranium Orefield, Ordos Basin and its enlightenment for uranium mineralization

China Geology, 2020
: The middle Jurassic Zhiluo Formation in the Dongsheng is comprised of a big set of green sandstone/mudstone with most of uranium orebodies occurring in close proximity to its footwall. By synthesizing field observations, region analysis, data collected

Geochemical reactions altering the mineralogical and multiscale pore characteristics of uranium-bearing reservoirs during CO2 + O2in situ leaching

Frontiers in Earth Science, 2023
CO2 + O2in situ leaching has been extensively applied in uranium recovery in sandstone-type uranium deposits of China. The geochemical processes impact and constrain the leaching reaction and leaching solution migration; thus, it is necessary to study ...

Multifractal Characteristics of Uranium Grade Distribution and Spatial Regularities in a Sandstone Type Uranium Deposit in Xinjiang, China

Fractal and Fractional, 2023
Based on the analysis of the spatial distribution of uranium grade in 348 boreholes of a uranium deposit in Xinjiang, the enrichment and spatial variation of uranium ore in two stopes of the deposit are discussed by using multifractal theory. The distribution characteristics of uranium ore of the two stopes are studied by multifractal parameters: the ...
