Experimental Studyon Sulfuric Acid Leaching of a Volcanic Uranium Ore Employing Microwave Pretreatment
摘要
Abstract
An iron￣rich volcanic uranium ore which was prepared for agitation leaching at am￣bient temperature and pressure was pretreated by microwave heating. The effect of microwave extraction from uranium ore was investigated,and after microwave pretreatment,the influence factors including mineral particle size,sulfuric acid concentration,liquid￣solid ratio,leaching time were compared with untreated.The results showed that the sulfuric acid consumption didn’ t increase but the needed leaching time did shorten after microwave pretreatment, as the mineral particle size which could gain relatively superior leaching rate although it was large;Compared with control group,the leaching rate of uraniumincreased,therefore,it was feasible to use microwave pre￣treat this uranium ore.The optimalleaching process parameters were 150μm particle size,20 g/L acid concentration,3 L/kg liquid￣solid ratio,and 9 hour agitation time.关键词
