[0002] At present, the ore leaching process involves column leaching, heap leaching, in-situ leaching and other processes. In the process of screening and optimizing process parameters in the laboratory, methods such as stirring leaching and column filling heap leaching are used. In the early stage of leaching, the in-situ leaching technology needs to blast the raw ore to crush it to a certain mineral particle size distribution. The distribution of mineral particle size is observed longitudinally. Often, the larger minerals are far away from the blasting center and are located at the top and bottom, while the smaller minerals are close to the blasting center and are located in the center of the interlayer. Due to the unique mineral particle size distribution law, the heap leaching column currently used in the laboratory is difficult to simulate the environment of the in-situ leaching process.
