Iron, Cobalt, Copper, Nickel, and Zinc Introduction to ...

Cobalt. Like nickel, cobalt in the Earth’s crust is found only in 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, silver-gray metal. The earth itself has a hot, dense core made largely of iron
