<p>PROBLEM TO BE SOLVED: To inexpensively, simply and steadily transport mined minerals onto the sea from a sea bottom.SOLUTION: A mineral lifting pipe 1, which has the inside 1a of a pipeline filled with seawater, which has a lower part 1b extended to the side of a sea bottom SB and which makes an upper part 1c reach a position on the sea, is used. Mined slurry-like minerals M are led in from a lower opening 1d of the mineral lifting pipe 1, and hydrogen gas H produced by electrolyzing the seawater on the side of the sea bottom SB is led in therefrom. A floating force of the hydrogen gas H makes the slurry-like minerals M transported onto the sea.</p> |
