Manganese nodules are small, dark, potato-shaped mixtures of different minerals, containing sources of useful metals such as manganese, iron, copper, nickel, lead, zinc and cobalt. The nodules are formed by about 24% of manganese, 15% iron, 1.5% of nickel and smaller abundances of the other elements.

…sea mining is shared, thus providing countries such as Gabon, South Africa and India an opportunity to extract their vast undersea resources without the risk of technological failures. In general, I believe that the manganese nodules should be exploited as a source of metal. Unimaginable technologies and knowledge await us, and I believe that undersea mining will lead to a huge industrial development wherever manganese nodules are in possession, regardless of the country's economical status.
