PROBLEM TO BE SOLVED: To separately collect useful metals and the like by a method wherein seabed resources are mixed into seawater and drawn up to a mother ship via a suction pipe, while useless seawater is returned into the sea. SOLUTION: In the method for collecting seabed resources, seabed resources are mixed into seawater to prepare a mixture, which is drawn up into a mother ship via a suction pipe, while solids in the mixture are separated into large particles and small particles. A mixture containing small particles is fed to a classification means, where the particles are separated into useful particles and useless particles, while a mixture containing useless particles is returned into the sea via a dumping pipe.
