توصيف بعض الخصائص الفيزيائية والكيميائية للفوسفات الخام في منجم خنيفيس

Abstract

Phosphate ore possesses important properties that have enabled its use in various industrial applications, including environmental pollution control. Therefore, it is important to investigate its qualitative properties as an indicator of expected performance in these applications. This study highlights a number of techniques applied to characterize phosphate ore in the Khneifiss mine physically, chemically, and mineralogically using various techniques, including X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), Field emission scanning electron microscopy (FESEM) and Energy-Dispersive X-ray spectroscopy (EDX). Thermo Gravimetric Analysis (TGA), Differential Thermal Analysis (DTA), Specific Surface Area (SSA) analysis (BET), and porosity were also performed on the phosphate ore. Metallurgical analysis showed that the raw phosphate is primarily composed of fluoroapatite, with graphite as a secondary metal phase. Elemental analysis (EDX) revealed a high content of silica and aluminum, along with traces of calcium, iron, and magnesium.
