摘要
To provide a mining device and a mining method of marine resources, and also a lifting device and a lifting method of marine resources, for making it possible to improve a mining efficiency.SOLUTION: This marine resource lifting apparatus 100 comprises a downhole motor 2 which includes a bit 90 driven by using a pressurized and transported leaching solution Ls for leaching as driving fluid M and a nozzle for discharging the leaching solution Ls used for leaching, from a discharge port formed in or near this bit 90 to the outside, thereby the rare earth can be mined while is being beneficiated from the rare earth mud by leaching digging. Therefore, mining efficiency can be improved.SELECTED DRAWING: Figure 6
