Thermodynamic analysis in the obtention of Calcium Phosphates from Phosphate Rock
2025
Overview
This paper deals with the thermodynamics of hydrometallurgical processes used in phosphate rock treatment. The stability of precipitated phases at different pH levels and molar concentrations in solutions containing phosphorus and calcium ions is analysed. The thermodynamic analysis was carried out by generating Pourbaix diagrams, species distribution diagrams and speciation diagrams using the Hydramedusa software. In addition, a XRD and SEM characterization of the different types of calcium phosphate found was performed to corroborate the thermodynamic results at different levels of pH and ion concentration. From this study, it was determined that hydroxyapatite and monetite can be obtained by hydrometallurgical processes with variations in pH and ionic concentrations of PO43- and Ca+, directly from the acid leach of phosphate rock.
