Laboratory study on leaching of a sandstone-type uranium deposit for acid in-situ leaching
摘要
Abstract
Ore samples were took from in-situ leaching experiment boreholes in a sandstone-type uranium deposit.Technological mineralogy study,agitating leaching and column leaching experiments were carried.The results show that the content of minerals consuming acid and deoxidized minerals is low.When sulfuric acid concentration was 10g/L,initial uranium content was 0.022 4％,and liquid-to-sol-id ratio was 1.91,leaching rate of column leaching experiments is 89.19％,acid consumption is 8.2 kg/t ore,acid consumption is 41.88 t/tU.Acid leaching technology is recommend for field in-situ leaching experiment,sulfuric acid concentration in confecting solution is 10 g/L,and oxidizing agent is needless during leaching process.关键词
