Abstract
In this research work, the direct roastingRoasting reaction of pure α-spodumene (LiAlSi2O6) with NaFNaF through thermodynamicThermodynamics simulationSimulation using the Equilib module included in the FactSage 8.2 software was studied. The molar ratios (RM) of LiAlSi2O6:NaFNaF: 1:0.5, 1:0.6, 1:0.7, 1:0.8, 1:0.85, 1:1, and 1:2.0 were analyzed in the temperature range (50–1200) °C and pressure of 1 atmosphere to determine the chemical species in equilibrium every 50 °C by Gibbs energy minimization. The most thermodynamically stable chemical species formed in all RMs were: LiF, NaAlSi3O8, and NaAlSiO4. The maximum percentage yield (PY) for the LiF species was 99% in the solid state starting at 250 °C, and in the liquid state at temperatura ≥850 °C for the 1:1 RM, with an excess of NaFNaF of 0.0008%. The obtained results demonstrated that direct roastingRoasting of α-spodumene using NaFNaF is thermodynamically favourable in the studied temperature range, which was confirmed by the formation of lithiumLithium fluoride in the solid or liquid phase and allowed to propose the reaction mechanism.
