中低含量复杂稀土矿稀土总量的快速分析方法

Rapid Analysis of Total Rare Earth Contents in Complex Rare Earth Ore with Middle and Lower Concentration

采用ICP-AES与化学分析方法如重量法、比色法联合应用,测定一系列矿样中稀土氧化物的含量,得出经验计算公式,建立测定同类型复杂稀土矿稀土总量快速分析的方法。

The contents of the rare earth elements in a series of rare earth ore samples were determined by ICP-AES combining with chemical analytical method,such as gravimetric method and spectrophotometric method. The empirience formula was obtained,and the method was established to rapidly and analytically determined the contents of total rare earth content in complex rare earth ore.
