As terrestrial mineral deposits are either depleting or of low grade, minerals from the deep-sea like the polymetallic nodules, cobalt rich crusts and polymetallicsulfides are considered as alternative sources for metals such as Cu, Ni, Co, Mn, Fe, that could be exploited in future by developing suitable technologies for mining as well as extracting metals from them.
