What gallium is used for?
Gallium is a soft, silvery metal used primarily in electronic circuits, semiconductors and light-emitting diodes (LEDs). It is also useful in high-temperature thermometers, barometers, pharmaceuticals and nuclear medicine tests. The element has no known biological value.
Is germanium used in phones?
Despite its failure as a transistor in the 1950s, germanium is now used in tandem with silicon in transistor components for some cell phones and wireless devices.
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.

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.
How many rare earths are there?
The rare earth elements (REE) are a set of seventeen metallic elements. These include the fifteen lanthanides on the periodic table plus scandium and yttrium. Rare earth elements are an essential part of many high-tech devices.
Who owns USA rare earth?
Pini Althaus, CEO, USA Rare Earth.
Does USA have rare earth?
Domestic efforts to extract rare earths are taking place in states including Wyoming, Texas and California, but the recent past provides cautionary tales, such as Molycorp, which reopened the longstanding Mountain Pass mine in California in the early 2000s, only to go bankrupt in 2015.
Is nickel rare earth?
Rare earth elements are not as “rare” as their name implies. 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].
