Abstract (English):	The process of natural drying of laterite ore has been the subject of modeling with the purpose of perfecting the technology used in its implementation. However, the models currently used for the energetic analysis of the process have not been experimentally validated. In order to solve this unsolved problem, the present work is developed in which, through the implementation of a multifactorial design of experiments, the experimental validation of the physical-mathematical models of the natural drying of laterite ore was developed. It was corroborated that the models describe the physical reality of the process with high accuracy (93.43 %), which can be improved through multidimensional modeling (2D and 3D) of the heat and mass transfer processes that characterize the object of study.

Abstract (Spanish):	El proceso de secado natural de la mena laterítica ha sido objeto de modelación con el propósito de perfeccionar la tecnología usada en su implementación. Sin embargo, los modelos actualmente utilizados para el análisis energético del proceso no han sido validados experimentalmente. Para dar solución a este problema se realiza el presente trabajo en el cual, mediante la implementación de un diseño de experimentos multifactorial, se desarrolló la validación experimental de los modelos físico-matemáticos del secado natural de la mena laterítica. Se corroboró que los modelos describen la realidad física del proceso con elevada precisión (93,43 %), la cual puede ser mejorada a través de la modelación multidimensional (2D y 3D) de los procesos de transferencia de calor y masa que caracterizan al objeto de estudio.
