Abstract

The thermal conductivity of lateritic ores was determined by using the transitory commonly known Hot- Ball method. An experimental facility was built and an experimental design was used for analyzing the property performance for three temperature values. It was obtained the thermal conductivity of lateritic reaches values from 1.5 to 3.5 W/ (m.k). An adjusted model of 0.98 correlations that estimates the thermal conductivity for the lateritic ores with temperature ranges of 40 °C to 70 °C was established.
