摘要
Abstract
Complex component sandstone-uranium deposits are mainly composed of conglomerate,sandstone and Slate.The uranium minerals are mainly uranite and titanium-uranium ores,including a small amount of pitchblende.The process mineralogy of complex component sandstone uranium ore was studied,and the leaching process was optimized.The results show that most of the uranium in the ore exists in the tetravalent form,and it contains a relatively large amount of calcium,magnesium,aluminium,iron and carbonate.The test results of acid leaching,enhanced leaching and column leaching show that the acid leaching process has a better effect.When 40～50 g/L H2SO4 is used as the leaching agent,the slag leaching rate of the acid column leaching is all greater than 90％.Comprehensively considered,it is recommended that the heap leaching process of-10 mm particle size ore be adopted in industrial production,and the mass concentration of the leaching agent H2 SO4 is preferably 40 g/L.关键词
