In the in-situ leaching uranium mining process, the cyclone suffers from pressure drop and energy consumption limitation, which restricts its wide application. Based on the similarity modeling method, the structural parameters, operational parameters and physical property parameters that affect the pressure drop of the hydro-cyclone in in-situ leaching uranium mining were comprehensively analyzed. The error between the calculated values of this model and the experimental values is within 15%, making it suitable for predicting the pressure drop of hydrocyclones in uranium leaching processes. Additionally, to further analyze the mechanism of pressure drop generation, the internal flow field of the cyclone was simulated by Fluent, which provides a theoretical basis for the optimization of hydrocyclone structure and working condition for in-situ leaching uranium mining.
