What are the 7 rare earth elements?
Heavy and light rare earth elements: The rare earth elements are often subdivided into "Heavy Rare Earths" and "Light Rare Earths." Lanthanum, cerium, praseodymium, neodymium, promethium, and samarium are the "light rare earths." Yttrium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium,
Are we running out of rare earth metals?
With reserves this large, the world would not run out of rare earths for more than 900 years if demand for the minerals would remain at 2017 levels.
Why are rare-earth metals so important?
"Rare-earth elements (REE) are necessary components of more than 200 products across a wide range of applications, especially high-tech consumer products, such as cellular telephones, computer hard drives, electric and hybrid vehicles, and flat-screen monitors and televisions.
What is so special about rare-earth metals?
The rare earths are 17 metallic elements, located in the middle of the periodic table (atomic numbers 21, 39, and 57–71). These metals have unusual fluorescent, conductive, and magnetic properties—which make them very useful when alloyed, or mixed, in small quantities with more common metals such as iron.
What is the most useful rare earth element?
Neodymium and praseodymium are some of the most sought-after light rare earth elements crucial in products such as motors, turbines and medical devices. Demand for them exploded in recent years with the growth of technology and will continue to climb amid the ongoing race to create a large electric vehicle market.
How are rare earth metals used in everyday life?
Rare earth metals and alloys that contain them are used in many devices that people use every day such as computer memory, DVDs, rechargeable batteries, cell phones, catalytic converters, magnets, fluorescent lighting and much more.
How many rare earth elements are there?
Rare earth elements (REE) are a group of 15 elements referred to as the lanthanide series in the periodic table of elements.
Is the earth running out of metal?
In addition, some research suggests that known primary metal supplies will be exhausted within about 50 years. Here we present an analysis of global metal reserves that suggests that primary metal supplies will not run out on this timescale.
Are we running out of neodymium?
The elements used in the magnets – neodymium, dysprosium and terbium – are in short supply and the west is in danger of losing access to them as China's domestic needs soar. Unfortunately, the green future of the UK and much of Europe also relies heavily on wind turbines rich in rare earths.
What are the rare earth minerals used for?
"Rare-earth elements (REEs) are used as components in high technology devices, including smart phones, digital cameras, computer hard disks, fluorescent and light-emitting-diode (LED) lights, flat screen televisions, computer monitors, and electronic displays.
What are the rare earth elements used for?
"Rare-earth elements (REEs) are used as components in high technology devices, including smart phones, digital cameras, computer hard disks, fluorescent and light-emitting-diode (LED) lights, flat screen televisions, computer monitors, and electronic displays.
What is neodymium and praseodymium used for?
Uses. In combination with neodymium, praseodymium is predominantly used in neodymium magnets used in a growing arena of high-tech applications. Praseodymium and neodymium oxides are used in welder and glass blower goggles to protect the eyes from yellow flare and UV light.
What can rare earth metals be used for?
REEs are used in a variety of industrial applications, including electronics, clean energy, aerospace, automotive and defence. Manufacturing permanent magnets is the single largest and most important end use for REEs, accounting for 29% of the forecasted demand in 2020.
What are rare earths and what are they used for?
"Rare-earth elements (REEs) are used as components in high technology devices, including smart phones, digital cameras, computer hard disks, fluorescent and light-emitting-diode (LED) lights, flat screen televisions, computer monitors, and electronic displays.
How many types of rare earth are there?

What is the earth running out of?
Running out of food – and planet
We currently overexploit Earth by about 75 percent and will need the equivalent of two planets by 2030 unless major changes are done.
What elements will we run out of?
Unfortunately, the long-term availability of all three of these critical elements – gallium, hafnium and indium – is in doubt. The American Chemical Society lists nine elements as facing a “serious threat” to supplies within the next 100 years (the other six are arsenic, germanium, gold, helium, tellurium and zinc).
Does Tesla use rare earth metals?
Electric drive motors come in many different designs the most popular being permanent magnet machines, but some designs do not require permanent magnets (and hence rare-earths). The induction motor utilizes a copper or aluminum cage on its rotor, this design has been used historically by Tesla for its Model S and X.
Will we ever run out of iron?
Iron is the most abundant element on earth but not in the crust. The extent of the accessible iron ore reserves is not known, though Lester Brown of the Worldwatch Institute suggested in 2006 that iron ore could run out within 64 years (that is, by 2070), based on 2% growth in demand per year.
What military products use rare earth metals?
More importantly to the Pentagon, they are also vital components of defense systems key to American military supremacy. Rare earth elements are used in a wide range of items: communications equipment, precision-guided weapons, night-vision goggles, and stealth technology, to name a few.
