氟碳铈镧矿中铈与富镧稀土分离新工艺的研究

New Technology of Divorcement Cerium from Rich lanthanum Rare Earth in Bastnaesite

用XRD和TGDTA热分析技术，研究了含独居石和氟碳铈镧矿的混合稀土精矿在100～1000℃焙烧过程中，添加CaO，NaCl时，REPO4和REFCO3的分解反应。

The reaction of the mixed rare earth concentrate including monazite ( REPO_4 ) and bastnaesite ( REFCO_3 ) decomposed by CaO and NaCl additives in the temperature of 100 ~ 1000 ℃ was studied by means of XRD and TG-DTA .

引用氟碳铈镧矿精矿中氧化稀土重量法的国家标准，在此经典的分析方法的基础上做了一些试验，重新整理、建立了新的焙烧矿中稀土总量的分析方法。

This paper established a new method for determination of total content of rare earths in bake ore by doing some tests based on national standard of determination of REO in bastnasite concentrate .
