Techno-economic Perspective on Processing of Polymetallic Ocean Nodules
2019This chapter looks at the techno-economic feasibility of processing of polymetallic nodules obtained from Pacific as well as Indian Ocean with an emphasis on cobalt market. Numerous processing routes have been developed for recovery of three (Cu + Ni + Co) as well as four (Cu + Ni + Co + Mn) metals.
