Abstract
Provided are an apparatus and method for solution mining using cycling process in which a solvent is injected into underground useful ores to dissolve the useful ores and then collected again to obtain the useful ores. The cycling solution mining method includes a boring process for excavating the underground up to an ore deposit, a fracturing process to generate cracks in the ore deposit, an injection process for inserting a mining apparatus including an insertion rod having a pipe shape up to a lower portion of the well to inject a solvent that dissolves the useful ores into the ore deposit through the insertion rod, wherein a rotation force is applied to the solvent discharged from the insertion rod to increase a diffusion force of the solvent, and a production process for collecting the solvent, in which the useful ores are dissolved, again.
