In view of the problems high acid consumption, blockage ore-bearing beds caused by iron ion precipitation and a low leaching rate in conventional sandstone-type uranium deposit, author put forward “low-acid oxygen technology” research. order to further clarify mechanism ore with oxygen, oxidation ferrous under acidic conditions, influencing factors process, kinetic simulation oxidizing minerals...

Iron oxide grain coatings in red sandstones contain trace metals that are released upon dissolution of the coatings. Analyses by ICP-MS following acid leaching show dissolved can constitute an ore-forming fluid, as hypothesized models for sandstone-hosted ore deposits. Median compositions 37 samples, mostly Triassic to Devonian age, from across Britain and Ireland 6.3 ppm copper, 2.4 cobalt, 10...
