国外铀矿石放射性分选的现状

摘要

经放射性分选提高矿石品位后可以降低铀的加工成本,还可以使一些低品位资源得以利用.近年来放射性分选的发展重新受到重视,以俄罗斯于2008年投产的一个大型放射性分选厂为例进行介绍.%The distribution of uranium in the earth's crust is more extensive, but the high-grade uranium deposit is very few. The processing costs of uranium can be reduced and some low-grade resources can be taken advantage of after the ore grade is raised by radioactive sorting. In recent years, the development of radioactive sorting receives attentions again. A large radioactive sorting plant in Russia, which was put into operation in 2008, is introduced,including process flow of ore treatment and technical parameters.
