In this work, a study was carried out on the effect of temperature as the main influencing factor of the rheological behavior of lateritic suspensions, raw material for the operations of pressurized acid technology (HPAL) used to obtain nickel and cobalt from of oxidized ores. From studies of X-ray diffraction, X-ray fluorescence, particle size analyzer and mathematical modeling, the behavior of the interactions and rheological characteristics of the analyzed samples were obtained. In this study it was concluded that the use of mathematical models that relate the temperature up to 90 °C and the energy parameters of the pumping system of flows, loads, hydraulic losses, power and efficiency, will allow finding ways to increase and stabilize the flow of fed hydromixture with a flow rate of 1600 m3/h and a solids concentration of 48% (w/w) and guarantee the efficiency of the technological process.
