Responsible for the Raman microscope in FWGP (801/P417).
1) Conventional and surface enhanced Raman spectroscopic investigation of mineral-collector interface processes:
Flotation is one of the most frequently used technologies in industrial mineral processing. This technology is based on the control of the wettability of the mineral surfaces using selectively adsorbing organic flotation collector molecules. This project we study specified mineral-collector model systems by means of Raman spectroscopy in order to get a molecular understanding of the mineral-collector interface.
2) Free electron laser beam supported scanning near-field optical microscopy (SNOM) of the mineral-collector interactions:
Based on the continuously tunable narrowband spectrum of the ELBE Free Electron Laser beam (FEL) infrared spectroscopic surface analysis is feasible below the detection limit of a commercial infrared spectrometer. This project aims to provide insight into the interactions and processes of the mineral-collector interface exploiting the advantages of FEL supported SNOM techniques.
