The seabed ore processing contains ore dressing and metallurgy. The ore dressing is based on the physical properties of different minerals in the seabed ore and adopts the methods such as gravity separation, flotation, and magnetic separation to separate the useful minerals containing manganese, nickel, cobalt, and copper from the gangue minerals.

Manganese Nodule — Wikipedia Republished // Wiki 2

The mineral composition of manganese-bearing minerals is dependent on how the nodules are formed; sedimentary nodules, which have a lower Mn 2+ content than diagenetic, are dominated by Fe-vernadite, Mn-feroxyhyte, and asbolane-buserite while diagenetic nodules are dominated by buserite I, birnessite, todorokite, and asbolane-buserite. The growth types termed diagenetic and hydrogenetic ...
