Cobalt and Manganese Extraction from Ocean Nodules by Co-Processing with Steel Metallurgical Slag
Polymetallic nodules, also called manganese nodules (due to their high content of this element), contain various valuable metals such as Cu, Ni and Co. These seabed minerals are a good alternative source of Co and Mn due to the decrease in the grade of ...

Slurry electrolysis of ocean polymetallic nodule
Abstract The ocean poly-metallic nodule was leached by using slurry electrolysis process in HCl-NaCl medium. The leaching rates of Mn, Co, Cu and Ni in the ocean poly-metallic nodule are all above 97%. Meanwhile, the high purity of electrolytic MnO 2 is also obtained as an anode product.

Response to “Cautionary Tales for Science‐Based Policy in Deep‐Sea Mining Governance”
ABSTRACT The policy analysis article “Cautionary Tales for Science‐Based Policy in Deep‐Sea Mining Governance” by Villar‐Muñoz (2026), https://doi.org/10.1111/1758‐5899.70185, addresses what the author perceives as “low‐certainty claims” in the context of deep‐sea mining and contrasts them with perceived “realistic scenarios” to argue that additional ...
