Cobalt is a chemical element; it has symbol Co and atomic number 27. As with nickel, cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, somewhat brittle, gray metal.
The Earth's crust is one "reservoir" for measurements of abundance. A reservoir is any large body to be studied as unit, like the ocean, atmosphere, mantle or crust. Different reservoirs may have different relative amounts of each element due to different chemical or mechanical processes involved in the creation of the reservoir. [1]: 18
Polymetallic nodules are found in both shallow (e.g. the Baltic Sea [7]) and deeper waters (e.g. the central Pacific), even in lakes, [8] and are thought to have been a feature of the seas and oceans at least since the deep oceans were oxygenated in the Ediacaran period over 540 million years ago.
Polymetallic nodules on the deep seabed in the CCZ Example of manganese nodule that can be found on the sea floor. Polymetallic nodules are found at depths of 4–6 km (2.5–3.7 mi) in all major oceans, but also in shallow waters like the Baltic Sea and in freshwater lakes. [23] [24] They are the most readily minable type of deep sea ore. [25]
Ocean – the four to seven largest named bodies of water in the World Ocean, all of which have "Ocean" in the name (see: Borders of the oceans for details). Sea has several definitions: [a] A division of an ocean, delineated by landforms, [6] currents (e.g., Sargasso Sea), or specific latitude or longitude boundaries. This includes but is not ...

The rare-earth elements (REE), also called the rare-earth metals or rare earths, and sometimes the lanthanides or lanthanoids (although scandium and yttrium, which do not belong to this series, are usually included as rare earths), [1] are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals. Compounds containing rare ...
