The modern world needs rare earth elements. The trace minerals that perform the roles that other raw materials cannot.
Q. What are the elements named after scientists?
Many elements were named after famous scientists. Some of the best-known elements include einsteinium (Albert Einstein), curium (Marie and Pierre Curie), rutherfordium (Ernest Rutherford), nobelium (Alfred Nobel), and mendelevium (Dmitri Mendeleev).

Q. What are 5 elements named after countries?
Five are named after currently existing countries:
- Polonium, named after Poland.
- Francium and gallium, both named after France.
- Nihonium, named after Japan.
- Germanium was named for Germany.
Q. Is gold a rare earth metal?
Rare earth metals include: rare earth elements—17 elements in the periodic table, the 15 lanthanides plus scandium and yttrium; six platinum group elements; and other byproduct metals that occur in copper, gold, uranium, phosphates, iron or zinc ores.
Q. Which country has the most rare earth metals?
China
Q. Who owns most rare earth minerals?
Q. Will we run out of rare earth metals?
The reserves of some rare earth minerals used in electronics, medical equipment and renewable energy could run out in less than 100 years. Rare earth minerals are naturally occurring resources, which cannot be recreated or replaced. Some minerals are only present in very tiny quantities.
Q. Does Australia have rare earths?
Australia has the world’s sixth-largest reserves of rare-earth minerals, though they remain largely untapped with only two mines producing them. The largest by far is the mine at Mt Weld in Western Australia, which is owned by Australia-based Lynas Corporation.
Q. What are heavy rare earths?
The heavy rare earth elements make up the balance and are significantly less abundant. These comprise europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium and yttrium. Rare earths each have their own individual demand drivers, challenges and technology innovations.
Q. What rare earth minerals are mined in Australia?
Currently, South Australia has no rare earth production but an estimated 1500 t of rare earths comprising the oxides of scandium (3%), yttrium (16%), lanthanum (38%), cerium (24%), praseodymium (0.7%), neodymium (1.8%), samarium (0.2%), europium (0.07%), gadolinium (0.4%), terbium (0.5%), dysprosium (3.3%), holmium ( …
Q. What is the most important rare earth metal?
The most abundant rare earth elements are cerium, yttrium, lanthanum and neodymium [2]. They have average crustal abundances that are similar to commonly used industrial metals such as chromium, nickel, zinc, molybdenum, tin, tungsten, and lead [1]. Again, they are rarely found in extractable concentrations.
Q. Is cobalt a rare earth metal?
Cobalt is primarily mined in the Republic of Congo and other parts of Africa that are labeled conflict areas. A quick Google search brings up several references to cobalt being referred to as a rare earth mineral, which isn’t true in either its grouping or necessarily its abundance.
Q. What are rare earth elements called?
The elements scandium and yttrium are also known as the “rare earths” because they were originally discovered together with the lanthanides in rare minerals and isolated as oxides, or “earths.” Collectively, these metals are also called rare earth elements (REEs).
Q. Why are lanthanides called rare earths?
They were called this because they are spread very evenly over the Earth, so it is hard to find a lot in one place. Promethium is rare, because it is radioactive, and decays. Cerium, one of the lanthanides, is the 25th most common element in the Earth’s crust.
