This invention is a recovery method for recovering mineral resources from the hydrothermal area under the ocean floor, the recovery method being provided with: (A) a step for excavating a hole extending from the ocean floor surface to the hydrothermal area through a guide base on the ocean floor surface, and then installing a casing in the excavation hole through the guide base and providing a hot water well; (B) a step for installing a mineral culture device on the guide base so as to cover the wellhead of the hot water well, and causing hot water ejecting from the wellhead to come into contact with seawater on the mineral culture device, thereby causing a mineral to deposit on the mineral culture device; and (C) a step for recovering, with the mineral culture device, the mineral deposited on the mineral culture device. |
