Comparison of Three Determining Methods of the Strontium,Calcium and Barium in Celestite Ores

Jiasheng Li

Abstract

The celestite ore mainly consists of strontium sulfate,barium sulfate and calcium sulfate.The strontium,barium and calcium are difficult to separate from each other,because all of them belong to alkaline earth metallic elements and their characteristics are quite alike.Three determining methods of strontium,barium and calcium content in celestite were compared in this paper.The results showed that volumetric method has high recovery,X-ray Fluorescence Spectrometry has high precision,and inductuvely coupled plasma-atomic emission spectrometry(ICP-AES) has great advantages in determining trace elements.
