| 简介 |
Provided is a seabed resource lifting device capable of causing deep sea mud containing rare earth elements to rise up from depths of over 5000 m. This seabed resource lifting device comprises : a transport hose comprising a first hose and a second hose that hang from a resource recovery vessel to the seabed; a crawler type collector provided with a first suction chamber that sends mud from the seabed to the first hose and a second suction chamber that sends mud from the seabed to the second hose; a water electrolyser that, by means of electricity supplied from the resource recovery vessel, electrolyses water to generate hydrogen gas and oxygen gas; and a gas injection device that injects the generated hydrogen gas and oxygen gas into the first suction chamber and second suction chamber respectively. Mud containing rare earth elements rises up with sea water by way of the buoyancy of the hydrogen gas or oxygen gas. |
