Our Case
  • Raman analysis: Detection of minerals and measurement of

    Raman analysis is a well-established method for finding the abundant minerals in an ore sample. In this study, Raman spectroscopy is tested as a method for rapid and contactless on-line mineral analysis. Rapidness might enable on-site analysis of rock drillcore, which in turn would lead to more cost-efficient solutions in mineral exploration.

  • Raman spectroscopy for mineral identification and

    That is because the Raman signal strength produced by a mineral in a rock or soil is not related in a simple way through the Raman scattering cross section of that mineral to its proportion in the rock, and the signal‐to‐noise ratio of a Raman spectrum is poor when a sample is stimulated by a low‐power laser beam of broad diameter

  • Raman effect and Hydrogen Bonds Semantic Scholar

    SummaryThe marked solubility of coumarin in aqueous mineral acids is attributed to the formation of complexes. That this takes place through hydrogen bonds is shown by a study of the Raman spectrum of these solutions wherein the carbonyl frequency is found to be considerably lowered, but still persists.

  • Raman spectroscopic analysis of real samples: Brazilian

    Oct 01, 2011· From a mineral processing point of view, the identification and proportion of the iron oxides/hydroxides is the most important. Goethite and hematite use to be these minerals, and hematite can easily be targeted by its diagnostic vibrations at 1326, 610 and 496 cm −1. Goethite also displays a nice spectrum, with at least five bands of good

  • Application of Raman Micro Spectroscopy and Micro-FTIR

    Lewis acids by accepting electrons from the mineral-sulfur, like EPS-complexed iron species, will preferentially strongly attracted. The selective attachment to mineral ores is associated with the occurrence of distinct dislocation sited, where sulphur atoms are accumulated. Conclusion Raman microspectroscopy and micro-FTIR mapping/
