Bacterial contributions to the formation of polymetallic nodules in the Pacific Ocean

Frontiers in Marine Science
Polymetallic nodules, widely distributed in the deep seafloor of the Pacific Ocean, are characterized by their abundance of diverse metal elements and considerable economic value. Previous studies have suggested a partial biogenic origin of these nodules.

Study on Travel Path Planning of Deep-Sea Nodule Collector During Collection Operation

Haiyang Kaifa yu guanli
Polymetallic nodules are a current focus in the development of deep-sea mineral resources. The mining process requires nodule collectors to travel over large areas on the seafloor for nodule harvesting, and the travel path has significant impacts on both

Macrobenthic communities in the polymetallic nodule field, Indian Ocean, based on multicore and box core analysis

Frontiers in Marine Science
Managing deep-sea mining is challenging due to limited data on species and habitat distribution, hindering decision-making. In less-explored polymetallic nodule sites in the Indian Ocean, management approaches are deemed unfeasible due to a substantial ...

Diversity and connectivity of bacterial communities in polymetallic nodule-rich abyssal plains (Eastern Tropical Pacific)

Frontiers in Marine Science
Polymetallic nodules of the abyssal seafloor are considered potential resources of nickel, cobalt, copper, as well as rare earth elements. The Clarion-Clipperton Fracture Zone (CCZ) hosts potential nodule mining sites licensed to several contractors for ...

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:
