NEODYMIUM

Neodymium and praseodymium are referred to as the elemental twins, as they were difficult to separate and possess a multitude of special properties.

Applications

  • Wind turbine generators create electricity using neodymium-iron-boron (NdFeB) magnets.

  • Neodymium yttrium aluminium garnet (Nd:YAG) are the most widely used lasers in commercial and military applications. It is used for cutting, welding, scribing, boring, ranging, and targeting.

  • Electric motors in hybrid "HEV" and electric vehicles "EV" use high-strength neodymium magnets to power the car.
  • Magnetic Resonance Imaging (MRIs) using NdFeB can be used to obtain an internal view of the body without radiation.

Interesting Facts

  • Neodymium-iron-boron (NdFeB) high-strength permanent magnets are the strongest in the world.

  • When switched to 'vibrate' mode, a miniature NdFeB magnet causes cell phones to vibrate when a call is received.

  • A thumbnail size, high-strength NdFeB magnet is so strong that when placed on a refrigerator door it cannot be removed by hand.

  • High-end audio headphones and speakers use NdFeB magnets to accurately reproduce sound and bass across a full spectrum.

  • YAG lasers are used to remove tattoos.

Discovery

Neodymium and praseodymium were discovered at the same time. Many chemists in the world believed that didymium was a mixture of these two elements, but were unable to separate them. Finally this was achieved at the Vienna Academy of Sciences on June 18, 1885 by chemist was Baron Carl Auer von Welsbach, who was studying in Heidelberg under the direction of German chemist Robert Bunsen. To separate didymium, Auer von Welsbach used multiple fractionations of ammonium didymium nitrate. His discovery resulted in two new elements, which he named neodymium and praseodymium. The more abundant new earth was neodymium, from the Greek neos didumous, meaning new twin.

Source

Large resources of neodymium are contained in LREE-enriched minerals. Neodymium occurs in the Earth's crust at an average concentration of 28 parts per million(ppm). The primary source of neodymium is from carbonatites and the LREE-mineral bastnäsite. Bastnäsite deposits in China and the United States constitute the largest percentage of the world's rare-earth economic resources. Neodymium is also a major constituent in the LREE-mineral monazite, as at Yangibana, which constitutes the second largest segment of rare-earth resources.

Neodymium oxide provides the major input to the value of Hastings’ Yangibana Project, where it averages approximately 2,800ppm in its resources - far exceeding the average concentration in the earth’s crust.
