Selective extraction of metals from polymetallic nodules of Central Indian Ocean Basin through chemical partitioning

Discover Geoscience
Polymetallic nodules occurring on the seabeds of the world’s oceans contain economically important metals such as Cu, Co, Ni, Pb, and Zn, primarily in the form of oxides and hydroxides. These nodules mainly consist of two intimately mixed mineral phases:

Common heritage of mankind: when science challenges legal concepts [PDF]

, 2014
By demonstrating the role of marine organisms in the formation and composition of deep-sea mineral resources, the aim of this poster is to demonstrate that legal definitions can sometimes be relatively simplistic and limited. Considering that on the deep

Accurate Identification Method of Small-Size Polymetallic Nodules Based on Seafloor Hyperspectral Data

Journal of Marine Science and Engineering
Polymetallic nodules are spherical or ellipsoidal mineral aggregates formed naturally in deep-sea environments. They contain a variety of metallic elements and are important solid mineral resources on the seabed.

Characterization and Reuse of Lithium‐ion Battery Cathode Material Recovered Through a Bacterial Process

Advanced Energy Materials, Volume 15, Issue 46, December 9, 2025.
A sustainable bacteria‐based lithium‐ion battery cathode recycling method is optimized using engineering biology. The resulting biomineralized manganese carbonate species is found to be easily converted into an electrode material, via simple calcination.

Rethinking Sustainable Batteries

Advanced Energy Materials, Volume 15, Issue 47, December 16, 2025.
This perspective examines sustainability across the entire battery lifecycle, from mining and manufacturing to use and end of life. Twelve principles for ‘green’ batteries are outlined, and it is argued that joint industrial, academic, and policy efforts are essential to building a truly sustainable energy future. Abstract Batteries will play a pivotal

Giant, highly diverse protists in the abyssal Pacific: vulnerability to impacts from seabed mining and potential for recovery

Communicative & Integrative Biology, 2020
Xenophyophores, giant deep-sea agglutinated foraminifera, dominate the benthic megafauna in the eastern equatorial Pacific Clarion-Clipperton Zone. This abyssal (>4000 m depth) region hosts major deposits of polymetallic nodules targeted for future ...

Giant protists (xenophyophores, Foraminifera) are exceptionally diverse in parts of the abyssal eastern Pacific licensed for polymetallic nodule exploration [PDF]

, 2017
Xenophyophores, giant, fragile, agglutinated foraminifera (protists), are major constituents of the abyssal megafauna in the equatorial Pacific Clarion-Clipperton Zone (CCZ), a region where seabed mining of polymetallic nodules may occur in the future ...

Experimental seabed disturbance effects on Chatham Rise deep‐sea meiofaunal communities, Southwest Pacific

New Zealand Journal of Marine and Freshwater Research, Volume 59, Issue 5, Page 1388-1421, December 2025.
ABSTRACT Growing global demand for deep‐sea resources may lead to increased pressure on benthic ecosystems. Here we examined changes in meiofaunal communities following an in situ physical disturbance experiment. A significant change in meiofaunal community structure in surface (0‐1 cm) and subsurface (1‐5 cm) sediments was observed immediately ...
