Jul 16, 2018· Manganese nodules are a potential source of copper, nickel, cobalt, iron, manganese and rare earth elements—metals used in electrical systems and for electronics like rechargeable batteries and touch screens. Deepsea nodule mining is expected to result in the destruction of marine life and seabed habitats over large areas.
Polymetallic nodules are rounded accretions of manganese and iron hydroxides that cover vast areas of the seafloor, but are most abundant on abyssal plains at water depths of metres. They form through the aggregation of layers of iron and manganese hydroxides around a central particle (such as a shell or small rock fragment), and ...
The mineral composition of manganesebearing minerals is dependent on how the nodules are formed; sedimentary nodules, which have a lower Mn 2+ content than diagenetic, are dominated by Fevernadite, Mnferoxyhyte, and asbolanebuserite while diagenetic nodules are dominated by buserite I, birnessite, todorokite, and asbolanebuserite. The growth types termed diagenetic and hydrogenetic ...
