Different minerals in tin polymetallic ores have varying degrees of grindability. When the particle size distribution of the crushed ore is unreasonable, sufficient liberation of useful minerals necessitates an increase in the grinding time, resulting in the easily grindable tin metal minerals being over-ground, further causing the loss of tin metal resources in the subsequent beneficiation process. In this study, a controlled shock wave technique based on electrical pulses was introduced to pretreated tin polymetallic ores. The effects on the physical properties of the tin polymetallic ore obtained using controllable shock wave pretreatment were investigated using an ultra-depth three-dimensional microscope, a universal mechanical testing machine, mercury porosimeter, and crushing tests. The crushing results showed that the average particle size of the pretreated ore crushing products was 17.98% smaller than that of the untreated ore crushing products. Furthermore, the particle size characteristic equation demonstrated that the particle size distribution of the pretreated ore crushing products was more reasonable. The mechanism analysis revealed that the internal structure and surface morphology of the tin polymetallic ore were fractured by the controllable shock wave based on the electrical pulse, the compressive strength of the ore after pretreatment was reduced by 91.23%, and the porosity value was increased by 5.38% compared with that of the untreated ore. Therefore, it is feasible to pretreat tin polymetallic ores with controllable shock wave before the crushing process, which reduces the ore crushing resistance and improves the particle size characteristics of ore crushing products.
