ISA is developing a mining code to regulate prospecting, exploration, and eventual exploitation of mineral resources in the Area, including polymetallic nodules, polymetallic sulphides, and _____ crusts.
- manganese
- cobalt-rich ferromanganese
- copper
- nickel
Answer: cobalt-rich ferromanganese
The three main deep-sea mineral types under ISA regulation are: polymetallic nodules (seafloor), polymetallic sulphides (hydrothermal vents), and cobalt-rich ferromanganese crusts (seamounts). The mining code aims to ensure environmental protection, equitable benefit-sharing, and scientific research.
