ABSTRACT:
An apparatus for hoisting ores from the deep-sea comprises a flexible endless member such as ropes or chains hanging from a buoyant ore-collecting vessel down to the bottom of the sea, a number of baggy nets fitted along the flexible endless member, a driving mechanism provided on the buoyant ore-collecting vessel for advancing the flexible endless member, and an ore collecting and filling mechanism for filling the collected ore into the baggy nets, which is towed on the sea bottom by a winch connected to a power and towing vessel floating ahead of the buoyant ore-collecting vessel. As a consequence of the advancing of the flexible endless member by the driving mechanism and the movement of the buoyant ore-collecting vessel, the baggy nets are successively lowered down to the sea bottom and hoisted therefrom with the ore filled by the ore collecting and filling mechanism.
