Mining and refining

Analysis of ores, feeds, slag, tails and metals

Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an ore body, vein or (coal) seam. Materials recovered by mining include base metals, precious metals, iron, uranium, coal, diamonds, limestone, oil shale, rock salt and potash. Whether the determination entails measurement of ores, feed, slags, or tailings in the mining process, X-ray Fluorescence (XRF) spectroscopy is one of the most commonly employed technique for these routine determinations of metal bearing minerals as well as metals and their oxides.

X-ray fluorescence (XRF) is the key technique for characterizing the element composition of geological materials. X-ray diffraction (XRD) is employed to quantitatively measure phase composition. Rietveld analysis of X-ray diffraction data is now recognized as the most powerful method available for quantitative crystalline phase analysis. Rigaku technology and expertise provide a number of unique solutions for these determinations.
