浙赣若干火山岩铀矿床成矿物理化学条件及与浸出采铀的关系

根据浙赣火山岩铀矿床地质特征及矿物包裹体资料，分别计算成矿热液中温度、盐度、硫逸度、氧逸度、ｐＨ 和Ｅｈ 值，认为成矿热液中铀呈［ＵＯ２（ＣＯ３）３４－ ］、［ＵＯ２（ＣＯ３）２２－ ］、［ＵＯ２Ｆ３－ ］形式迁移，并分析了浙赣火山岩铀矿床成矿的物理化学环境，同时讨论了研究火山岩铀矿成矿物理化学条件对地（堆）浸出采铀的关系

THE RELATION BETWEEN LEACHING URANIUM AND ORE-FORMING PHYSICOCHEMICAL CONDITION OF ZHEJIANG-JIANXI VOLCANIC TYPE URANIUM DEPOSIT

This paper calcultates the temperature,saltness,sulfur fugacity,oxygen fugacity,pH value,Eh value of mineralizing solution,on basis of the geological character and mineral inclusion data in Zhejiang Jiangxi volcanic type uranium deposit,considers that uranium in mineralizing solution migrate in UO 2(CO 3) 3 4- ],UO 2(CO 3) 2 2- ],UO 2F - 3]form,analyses the physicochemical environment of Zhejiang Jiangxi volcanic type uranium deposit,and discus ses significance of in situ leaching(heap leaching)uranium about research of physicochemical condition in volcanic type uranium deposit.
