Rare earth/strategic metals are industrial metals that are typically mined as by-products in operations focused on precious metals and base metals. Compared to base metals, they have more specialized uses and are often more difficult to extract.
Currently, about 49 elements in the periodic table are considered rare earth/strategic metals. They include such elements as cerium, manganese, titanium and tungsten. Strategic metals are used in a variety of technologies including jet engines, hybrid cars, steel alloys, wind turbines, flat screen televisions and cellular phones.
Rare earth metals, a subset of strategic metals, are a collection of 17 chemical elements that are essential in many of today’s most advanced technologies, with particular applications in electronics.
