Fundamental studies for sensor based sorting on several
industrially relevant minerals and a lead containing glass
sample are presented. The examined minerals were: Talc, Magnesite,
Calcite, Fluorite, Scheelite and Chalcedony. The methods of
investigation were UV-VIS-NIR reflection spectrometry between
200 - 2500 nm and UV induced solid state fluorescence measurements
with excitation between 200 - 380 nm and emission detection
between 400 - 900 nm. A common quenching mechanism for
UV-induced fluorescence is discussed. Artefacts and sources of
error for solid state luminescence measurements are mentioned.
