大多数磷矿中都伴生有铀。在磷矿加工过程中综合回收其中的铀,早已为人们所重视,其回收方法已经由试验室研究发展为工业应用。目前,美国、加拿大、摩洛哥等国已相继建立了铀回收车间,预计到2000年,美国可以从湿法磷酸中回收70000吨铀(以U_3O_8计)。 铀在磷矿中的赋存状态与综合回收的关系很大,因而早期的工作已注意了对这一课题的 Uranium is found in most phosphate rock. The comprehensive recovery of uranium from phosphate rock processing has long been valued by people and its recovery method has been developed from laboratory research to industrial application. At present, the United States, Canada, Morocco and other countries have successively established uranium recovery workshops. It is estimated that by 2000, the United States can recover 70,000 tons of uranium (calculated as U_3O_8) from wet-process phosphoric acid. Uranium in phosphate rock in the state of occurrence and comprehensive recovery of a great relationship, so early work has been paid attention to the subject
