The purpose of this work is to contribute to the improvement of Phosphate ore characterization in order to optimize P2O5 recovery. This paper depicts how, by strategically combining different analytical techniques like X-ray Diffraction, X-Ray Fluorescence powder/beads, Infra-Red Spectroscopy, and Thermogravimetric Analysis, it is possible to obtain a very accurate picture of the ore, leading to a better control of the beneficiation process. As this method furthermore allows the speciation of carbonates (Calcite, Dolomite, Francolite), it is also valuable for the management of complex fertilizers manufacturing where Calcite and Dolomite behave differently.
