Process for treating uranium ores in one, two or more stages, characterized in that in a pre-attack a feed with a concentration of more than 30% in solid is treated, which comes from one or more acid leaching stages carried out at a temperature higher than the ambient temperature. . The pre-attack is carried out at room temperature or slightly higher, depending on the thermal balance of the currents that are mixed. After this pre-attack a solid-liquid separation is carried out with the addition of a coagulating agent from which the fertile solution is obtained and a stream in which the mineral is taken to the first attack stage.
