Constraints of the sequence stratigraphic structure of uranium-bearing series on mineralization in Qianjiadian uranium deposit, Songliao Basin

open access: yes地质科技通报, 2021
Understanding the stratigraphic structure of uranium-bearing rock series in sandstone-type uranium deposits and its constraints on uranium mineralization is the basis of understanding the uranium metallogenic regularity and mineralization. In this paper,

Column bioleaching of sandstone type uranium ore deposit

open access: yesPacific 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.
