What are rare earths? - Lynas Rare Earths
Rare Earths are a group of 15 elements in the periodic table known as the Lanthanide series. Rare earths are categorised into light elements (lanthanum to samarium) and heavy elements (europium to lutetium). The latter are less common and consequently more expensive. Chemically, rare earths are strong reducing agents.
