The marine manganese deposits (MMD) include manganese nodules (also called polymetallic nodules or ferromanganese nodules), slab-type ferromanganese encrustations, and cobalt-rich crusts. Although first recovered in 1868 from the Kara Sea, off Russia (erstwhile the USSR), probably the first detailed scientific investigation of MMD was
