| Application of optical, chemical and thermal methods to the analysis of inorganic and organic constituents in phosphatic pellets (Tunisia) (2005) | |||||||||||||||
Abstract | |||||||||||||||
| A study of pellets, phosphatic grains whose size lie between 50 and 200 m, of the Tertiary Gafsa Metlaoui basin (Tunisia) has been performed by X-ray diffraction, IR spectroscopy, CNS elementary analysis, microscopy (photonic, conventional MEB and Cryo-MEB), Rock-Eval analysis. The X-ray diffraction shows that the fundamental mineral within these phosphatic pellets is carbonate-fluorapatite or francolite. | |||||||||||||||
