Nickel ore
Nickel is a chemical element. Its chemical symbol is Ni, its atomic number is 28, and its atomic weight is 58.69; it belongs to Group VIII of the periodic table. In ancient times, the Egyptians, Chinese, and Babylonians all crafted objects from meteoric iron with exceptionally high nickel content, and in ancient China, nickel ores produced in Yunnan also exhibited very high nickel concentrations. In 1751, the Swedish chemist A.F. Cronstedt obtained metallic nickel by reducing niccolite with charcoal; the English name for nickel derives from the German term “Kupfernickel,” which means “false copper.” Nickel occurs in the Earth’s crust at a concentration of 0.018%, and its principal minerals include pentlandite, garnierite, millerite or violarite, and niccolite. Furthermore, manganese nodules on the ocean floor contain substantial nickel reserves, making them an important prospective resource for nickel.
