Express Assessment of Apatite Content in Apatite–Nepheline Ores of Ultrabasic Alkaline Complexes Based on Its Luminescent Properties (The First Study Stage)

The article presents the results of first study stage aimed at analyzing luminescent properties main and minor minerals composing apatite–nepheline ores host rocks in deposits Khibiny rock massif (Kola Peninsula, Russia). purpose work was a search stable identification feature providing fast safe determination fluorapatite mineral mixture solving technological tasks, namely sampling borehole walls open pits. includes studies carried out on pure mono-fractions four occurring possessing obvious properties: fluorapatite, nepheline, calcite, sodalite. authors have revealed luminescence spectra these established correlation their spectral characteristics with literature data consistency. However, high intensity sodalite wide band can complicate by spectrum many cases. Therefore, it is reasonable to use color rather than characteristics.
