Description

technical field

[0001] The invention relates to the technical field of in-situ leaching mining, in particular to a system and a method for breaking metal ore layers caused by instantaneous electric pulses. Background technique

[0002] In-situ leaching refers to injecting the solution from the surface into the deep ore body through the liquid injection drilling. During the flow of the solution in the ore body, the leaching reaction with the target mineral occurs, and the obtained soluble metal ions enter the solution, and the solution is discharged through the pumping hole. Elevate to the surface, and finally obtain metal products through extraction-electrowinning process. This technology can realize unmanned underground operation, avoid environmental damage caused by ore body excavation, and has the characteristics of high safety, low pollution and low cost. Among them, the flow process of solution in the ore body is the core of the whole leaching process, and the study of...
