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

Minerals (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 phreatic oxidation), the orebody of the HLJ uranium deposit is tabular-shaped and multi-stratiform ...

The Role of OM in the Formation of Sandstone-Type Uranium Ore—A Review

Minerals (Basel, Switzerland)
Sandstone-hosted uranium deposits represent one of the most critical global uranium resources suitable for in situ recovery, with their formation closely associated with organic matter (OM). We conducted a systematic literature review to synthesize over 100 published studies sourced from authoritative databases (Elsevier, Google Scholar, Web of Science,

Law and Mechanism of Different Electric Field Modes Enhancement Alkaline Leaching Sandstone-type Uranium Ore

Yuanzineng kexue jishu
China’s uranium resources are rich in reserves and deposits, but they are mainly low-grade uranium ores with low content of uranium. Sandstone-type uranium ores are mainly mined by in-situ leaching (ISL), but when the carbonate content is high, their ...

Characterization of ore-forming fluids in the Tamusu sandstone-type uranium deposit, Bayingobi Basin, China: Constraints from trace elements, fluid inclusions and C–O–S isotopes

Ore Geology Reviews, 2019
Abstract The Tamusu deposit is a large sandstone-type uranium deposit discovered in recent years in the Bayingobi basin, Inner Mongolia. Hydrothermal activity was recorded by veins in this deposit, but its relationship with uranium mineralization has not been clarified.
