Manganese nodules, typically half-buried in comparatively flat deep-sea sediment at a depth of 4000–6000 m, are rich in numerical metallic elements [1,2].The gradual consumption of land mineral resources means that manganese nodules could be important candidate resources as alternatives to terrestrial mining.

Rock Hammers & Picks. Rock hammers and picks are two of the most common tools used for gold mining. A rock hammer is a tool that is used to break rocks, while a pick is a tool that is used to remove rocks from the ground. Rock hammers come in a variety of different sizes, and they are usually made of steel or iron.

Currently proposed methods of nodule mining include the deployment of a mining vehicle, typically a very large machine resembling a three-story tall tractor, to the seafloor. Once on the seabed, the vehicle will vacuum the top four inches of the seabed, sending the sediment, rocks, crushed animals, and nodules up to a vessel waiting on the surface.
