This article shows the main experimental results related to measuring dielectric properties of Pyrite ore mineral samples as a function of temperature, and their effect on the heating behavior of the samples. It was found that the real, ϵ ’ ( T ), and imaginary, ϵ ’’ ( T ), components of permit-tivity are strongly dependent on temperature. The model that best fitted experimental data for ϵ ’ ( T ) and ϵ ’ ( T ), was a Gaussian correlation, reaching R 2 values over 0.995. Besides, and under certain conditions, it was possible to roast the mineral even better than with an electric furnace, while requiring less processing time (about 77.5% less) and with lower electrical energy consumption (about 80.8% less). Additional exploratory tests revealed that microwaves can be used to smelt a roasted mineral ore with time reductions of about 90%, while keeping recov-ery margins above 95%. Next stages of research should be directed to using a single mode applicator for processing higher volumes of mineral at pilot plant scale.
