Resumen:
According to the model, the temperature has the greatest influence on Li extraction because it controls the rate of fluorination reaction and NH4HF2 decomposition. The amount of NH4HF2 and time also have a positive influence on the process. These allow to improve the diffusion of the liquid NH4HF2 through the mineral structure, increase the contact surface and the interaction time.
