• Resumen

  • The present work expose the mineralogical characterisation of PST samples obtained from an industrial Mediterranean area. For this purpose the technique of x-ray diffraction - method of crystalline powder and SEM have been used. The samples of TSP (Total Suspended Particles) were obtained by means of High Volume Captors and a filter media was used. Firstly an extraction of the particulate material from each sample was made and analysed by DRX according to three hydration degrees. The majority and minority phases were identified. Secondly the application of a semi-quantitative and guiding method of the identified mineral phases allowed us to study the monthly and weekly evolution of the material composition. Finally, some samples were analysed by a scanning electron microscopy (SEM)in order to identify and corroborate the presence of vitreous particles and crystalline phases at high temperature. The mineralogical results showed a high percentage of clays in the samples and the presence of minerals used like raw materials (K-Ba feldspar, zircon silicate). The SEM analysis confirmed the presence of vitreous particles and crystalline phases typical of high temperature processes.
