    for uranium This in turn will make it necessary to extract uranium from ores of lower grade than are usable at present Since the resources of these ores are at least ten times as great as those of ores from which uranium can be extracted at current costs, the processing of such lowgrade ores is of particular interest to many countriesLaboratory testing of uranium ores is an essential step in the economic evaluation of uranium occurrences and in the development of a project for the production of uranium concentrates Although these tests represent only a small proportion of the total cost of a project, their proper planning, execution and interpretation are of crucialMANUAL FOR URANIUM ORE PROCESSINGTo make the uranium ores more susceptible to high uranium extraction by leaching, mined ores must be Fig 1 Uranium mineralization in the form of rhomboedric crystals (probably coffinite) in the highly porous sandstones with carbonate cement Fig 2 Uranium mineralization fills spaces between micas crystals 522 J Radioanal Nucl Chem (2015) 303Mineralogy and uranium leaching of ores from Triassic

  • Separation of thorium from uranium ore | SpringerLink

    Uranium ore is classified by grade, with highgrade ore containing 1 to 4 wt% uranium, medium grade with 01 to 05 wt% uranium and lowgrade with less than 01 wt% uranium Uranium is often found as uranite (previously known as pitchblende) in highgrade ores, which contains mixed uranium oxide compounds [13, 14]The recovery of uranium from quartzpebble conglomerates of the Witwatersrand Basin is accomplished through sulphuric acid dissolution under oxidising conditions At Cooke Section on the West Rand Goldfield, the extraction process has been plagued by low to moderate yields on the order of 40 to 75%, as opposed to a target recovery of 80%A mineralogical perspective on the recovery of uraniumIn general, the indirect bioleaching of uranium from uranium ores occurs according to the reaction (2) (Bosecker, 1997 ): UO 2 + Fe 2 (SO 4 ) 3 → UO 2 SO 4 + 2FeSO 4 (PDF) A comparison of uranium recovery from lowgrade
