【Abstract】 In this paper presents the study on nitrate as oxidant in acid in situ lcaching of uranium. The test results show that nitrate can effectively oxidize Fe 2+ in absorpted effluent.but the dynamic feature of nitrate [KG-9]s oxidizing Fe 2+ is inferior to that of H 2O 2.The insoluble U(Ⅳ) of the ore can be oxidized and leached satisfactorily with the using of nitrate.The nitrate as oxidant for leaching can meet the requirements of acid in situ leaching process.更多还原
