Outline
With the continuous development of in-situ leaching uranium mining technology, how to effectively remove solid particles has become a key issue of in-situ leaching uranium mines. In this paper, the removal method of solid particles in an in-situ leaching uranium mine was studied in depth, and the process was optimized. Firstly, the principle of in-situ leaching uranium process was summarized. The sources of solid particles and their negative effects on production were described in detail, such as increasing the operating pressure of the system, reducing the permeability of the ore layer, and affecting the efficiency of uranium recovery. Then, the existing solid particle removal methods were analyzed. On this basis, a series of optimization strategies for solid particle removal process were proposed, including improving resin cleaning cycle, optimizing resin tower sequence, and increasing discharge process in adsorption process. Through experimental research and practical application case analysis, it is verified that the optimized process has significant effects in improving the removal efficiency of solid particles and improving the stability of system operation. The research results provide important technical support for the efficient production of in-situ leaching uranium mines.
