XRF is a fast, accurate and easy tool for different analytical applications in the mining industry. It provides on-site analysis of ore samples with minimal sample preparation, reducing the time for lab assay from days to minutes. Usage of the fundamental parameters method allows analyzing an ore sample without the need for any calibration standards. The capability of precise analysis of light elements is very important for understanding sample mineralogy, and it is critical for analysis of certain types of minerals such as bauxite and limestone. During exploration, handheld XRF analyzers are good for fast screening of vast areas due to the light weight and mobility of the instrument. Integration of the GPS to the handheld XRF analyzers allows storing GPS coordinates with each measurement. GPS data can be imported then to any GIS application for geochemical mapping. For mining, XRF provides easy ore grade control and allows making quick decisions. Analysis of ore concentrates during the enrichment process is also a simple task for XRF. Both primary elements and trace elements can be accurately measured due using the fundamental parameters method.
