Determination of Major and Minor Elements in Baryte Ores by X-ray Fluorescence Spectrometry with Fusion Sample Preparation

In order to avoid the influences of mineral structures and reduce matrix effects, a fusion method has been developed as the sample preparation step for the analysis of 9 major and minor elements components in baryte ores with X-ray fluorescence spectrometry. The fusing conditions were thoroughly studied for the optimization of instrument parameters, and then corresponding working curves were established. The relative standard deviations (RSD) for each element analyzed was less than 10%, and analysis accuracy was in good agreement with ISO 9507. Experimental results indicated that this method was accurate, and well suited for the analysis of baryte ores.
