Mining and Refining
How are analytical techniques used in mining and mineral processing?
Rigaku analytical technologies help characterize ores, concentrates, tailings, slags and refined materials from exploration and mineral research through process control and final-product quality assurance. X-ray fluorescence (XRF) determines elemental composition and can be used to monitor ore grade and process chemistry, while X-ray diffraction (XRD) identifies and quantifies minerals and other crystalline phases.
Thermal analysis can complement these techniques by measuring reactions and transformations that occur during heating, including dehydration, decomposition, oxidation and phase changes. For specialized mineralogical research, single-crystal X-ray diffraction can provide detailed three-dimensional crystal structures of individual mineral phases.
