ABSTRACT:
Methods and apparatus for underwater mining by inducing upwelling of water and entrained minerals or other materials through a conduit from an intake which may move within the body of water by unbalanced forces developed therein by such upwelling to a recovery field which may comprise a vessel floating on the water and which may also be moved by the upwelling water. The outlet of the conduit to the recovery field is positioned below sea level and the velocity of the upwelled water in the recovery field is gradually reduced to induce selective separation of the entrained minerals or other materials.
