碱熔脱硅与酸溶不脱硅稀土总量测定对照

Comparison of Analytical Results the Rare Earths in the Bake Ore Aggregates from Removing Si and Keeping Si Alkali Melt

本文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碱熔法脱硅与酸溶不脱硅的稀土总量的对照实验,重新整理、建立了新的焙烧矿中稀土总量的分析方法。采用此分析方法测定焙烧矿中的稀土总量,准确度高、精度高、稳定性也很好,且适应焙烧矿的生产工艺的需要。

This paper quotes the national standard of the weighty method of oxidation rare earths in the concentrate .To do some tests in the base of the classical analytical method and put them in order again. Comparison of the analytical results the rare earths aggregates from reoving Si and keeping Si alkali melt .To set up a new way of the determination of rare earths aggregate in the bake ore.The degree of accuracy and the precision are high through the analytical method to determinate rare earths aggregates in the bake ore, and the stabilization is good. The analytical method is suitable to the demand in the production technological process.
