Measuring Iron in Ore Materials Using EDXRF

A new empirical method was announced by Applied Rigaku Technologies for the elemental analysis and measurement of iron (Fe) content in mining materials. Elemental analysis plays a key role in screening samples at mine sites and in difference stages of ore processing in order to ensure proper extraction and process control. Careful monitoring of major and minor elements is performed in the ores, slags, concentrates, and tails during the process of smelting.


The new empirical approach demonstrates the ability of the NEX QC energy dispersive X-ray fluorescence (EDXRF) elemental analyzer to meet the industry challenges.

NEX QC EDXRF Elemental Analyzer

The Rigaku NEX QC provides low-cost EDXRF analysis to explore metals in ore samples. The system is a simple yet fast technique ideal for performing elemental analysis along the entire processing line. It is equipped with a high performance semiconductor detector and 50 kV direct excitation in order to provide improved sensitivity at a low cost. This makes it an ideal instrument to analyze ore materials.

The NEX QC analyzer can be easily transported for mine site screening, thanks to its smaller footprint. It is robust enough for use in central lab and rugged enough to be used in the smelting operations.

Sample Preparation and Analysis

Samples were prepared by grinding and drying the ore material into a homogeneous powder, followed by transferring and compacting the powder into a standard 32 mm XRF measurement cell with a manual sample press. Then, the NEX QC EDXRF analyzer was used to perform the analysis.


The results of the analysis demonstrate the ability of the NEX QC EDXRF analyzer to identify and quantify elemental composition of many different iron materials. With a sophisticated touch screen interface and small footprint, the analyzer is transportable, robust, and reliable. These qualities make it a suitable solution for use in iron production.
