A historical perspective on deep sea mining for manganese

A historical perspective on deep sea mining for manganese

Jul 01, 2019 The mining of manganese nodules is expected to have a more substantial impact on global metal markets as well as on the marine environment in the future compared to seafloor massive sulphides. By comparison, the exploration for Co-rich ferromanganese crusts and the technology to extract them are still in their infancy ( Petersen et al., 2016 ...
