Simultaneous Leaching of Seafloor Massive Sulfides and Polymetallic Nodules [PDF]
Minerals, 2019 Simultaneous leaching of seafloor massive sulfides (SMS) from Loki’s Castle on the Arctic Mid-Ocean Ridge (AMOR) and polymetallic nodules (PN) from Clarion Clipperton Zone (CCZ) of the Central Pacific Ocean was studied. Leaching tests were conducted using sulfuric acid and sodium chloride, at a temperature of 80 °C for 48 h under reflux.

Dynamic Traction of Deep-Sea Polymetallic Nodule Collector
Journal of Marine Science and Engineering, 2023 The ocean is extremely rich in mineral resources. To cope with the shortage of land mineral resources, countries are focusing on the development of deep-sea mineral mining technology. Owing to its superior traction performance, the deep-sea polymetallic nodule collector (DPNC) has become the preferred solution for ocean mining.

Slurry electrolysis of ocean polymetallic nodule
Transactions of Nonferrous Metals Society of China, 2010 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.
