Method of lifting and mining marine resources, balun for lifting marine resources and marine resource pumping apparatus equipped with the same

摘要

An object of the present invention is to provide a method for raising and demining marine resources that can eliminate the need for extending piping for demining from the sea to the sea floor, a balun for marine resource extraction and a marine resource pumping apparatus equipped with the same. A method of pumping of marine resources stores a mixture Ma of an emulsion Em, which has a specific gravity lower than that of seawater, and a rare earth mud Dr, which is a marine resource mined on the sea bottom D, in the ocean 1 It includes a mining process (Pr) and a lifting process (Ps) in which the balun 1 is floated by the difference in specific gravity between the balne 1 itself and the seawater W in a state of storing the mixture Ma.
