This paper discusses uranium extraction and refining at the hydrometallurgical state as well as in radiochemical production. The authors advise carrying out the extraction process at an elevated temperature, especially as the phase separation rate usually also increases. A change in the extractor hydrodynamics with temperature variation can also exert an influence. The optimum process conditions are determined by considering the following factors: effect of the temperature on contact between mutually saturated solutions; drop size; disperse phase retention; the flooding load; and efficiency. The authors conclude that the data presented indicate that the effect of temperature on the characteristics of the extraction processes in a column must be taken into account in determining the optimum process conditions, performing hydrodynamic tests, comparing equipment and packing of various types.
