Abstract: In the present investigation, a study of the drying kinetics of lateritic mineral samples is carried out and the adjustment of the theoretical models exposed in the specialized literature with the data obtained during the experimentation is evaluated. The variation of humidity, drying speed, and drying time for temperatures between 100 ºC and 500ºC were analyzed. In addition, for each of the temperatures studied, the adjustment constants of the theoretical models were determined. From the comparison of the theoretical models, it is established that the Modified Page model is more adjusted to the behavior obtained from the lateritic mineral. From the analysis of the drying curves, it is concluded that the lateritic mineral has a non-hygroscopic behavior.
