Uranium recovery from sandstone-type uranium deposit by acid in-situ leaching - an example from the Kujieertai

Hydrometallurgy, 2020
Abstract The factors influencing uranium recovery in water-rock systems during acid in-situ leaching (ISL) were studied at the Kujieertai uranium deposit in Xinjiang. Using an ISL unit, a field leach trial (FLT) had been carried out to test the sequential effects of a leaching solution without oxidant (H2SO4 solution 4–8 g/L) and a leaching solution ...

Diversity of Microbial Community in Shihongtan Sandstone-Type Uranium Deposits, Xinjiang, China

open access: yesGeomicrobiology Journal, 2012
Investigation of microbial communities in uranium deposits will be beneficial for understanding the indigenous microbial impacts on uranium-mineralization as well as developing appropriate remediation and long-term management strategies of uranium-contaminated repositories.

Genetic Mechanism of Tabular-Shaped Orebody of the Hailijin Sandstone-Type Uranium Deposit in the Songliao Basin: Constraints on the Clay Mineralogy of Ore-Bearing Sandstone

open access: yesMinerals (Basel, Switzerland), 2023
The Hailijin (HLJ) sandstone-type uranium deposit was newly discovered in the southwestern Songliao Basin in recent years. Different from the roll-front orebody of the sandstone-type uranium deposits with (phreatic oxidation) interlayer redox origin (or ...

Uranium Isotopes in Groundwater: Their Use in Prospecting for Sandstone-Type Uranium Deposits

Journal of Geochemical Exploration, 1977
ABSTRACT Cowart, J.B. and Osmond, J.K., 1977. Uranium isotopes in groundwater: their use in prospecting for sandstone-type uranium deposits. J. Geochem. Explor., 8: 365–379. The relative abundances of dissolved 238U and its daughter 234U appear to be greatly affected as the uranium is transported downdip in sandstone aquifers. In an actively forming

Methodology and exploration for sandstone-type uranium deposits

Mineralium Deposita, 1979
Mobility of uranium with ground water in near surface earth conditions and its association with sandstone formations of continental depositional environments require an increase in the understanding and application of depositional characteristics in exploration.

Fission-track dating of sandstone-type uranium deposits

Geology, 1982
A procedure has been developed to make use of quartz grains in sandstone-type uranium deposits as external detectors of spontaneous fission events in interstitial uranium. Fission-tracks must be counted on a large number of grain surfaces because uranium distribution is not uniform on a grain-to-grain scale.

Geochemical characteristics of Dongsheng sandstone-type uranium deposit, Ordos Basin

Chinese Journal of Geochemistry, 2007
Generally, sandstone-type uranium deposits can be divided into three zones according to their redox conditions: oxidized zone, ore zone and reduced zone. The Dongsheng uranium deposit belongs to this type. In order to study its geochemical characteristics, 11 samples were taken from the three zones of the Dongsheng uranium deposit. Five samples of them
