Techno-economic Perspective on Processing of Polymetallic Ocean Nodules

2019
This 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.

Technical and Economy Study of Polymetallic Nodules Seabed Mining

2014
At present there are many proposals on individual technical devices suitable for deep-sea mining of polymetallic nodules. Now is the time to define elements of the system of mining. The structure of such a system may consist of one or more vessels at the sea level, one or more mining collectors moving on the ocean floor, buffers, and vertical pipes and

Estimation of Polymetallic Nodule Abundance Based on Seafloor Photography

Journal of Marine Environmental Engineering
In this study, we aim to enhance the precision of estimating polymetallic nodule resources in the Western Pacific Ocean by employing a traditional deep-sea camera method supported by sampling. A series of image pre-processing techniques are applied, and an equation is developed to determine the weight and surface area of the nodules.
