硅铍钇矿全分析

Analysis of Gadolinite

硅铍钇矿是一种含钇族稀土元素和氧化铍为主的重要工业矿物,可以简单的表示为:BeFeY_(2)O_(3),2SiO_(2),其主要部分大致含量为:SiO_(2)23.9%、Y_(2)O_(3)51.8%、FeO14.3%、BeO10%。铍和稀土元素,在国民经济和国防中,有着极其重要的价值。关于硅铍钇矿的分析,目前分析流程较少.

Beryllium is separated from REE and aluminum with zerolit 225 cation exchanger,the eluant for beryllium is 2.0M HNO_(3)in 70%methanol.The recovery was nearly 100%for 5mg Be.The other elements were eluted by using hydrochloric acid of different concentration,and determined by rotine method.
