The rare earth is generally separated in an oxide state, although the reserves on the earth are huge, the smelting and purification difficulty is large, and the rare earth is obtained. Generally, rare earths on earth exist in the form of rare earth oxides. Rare earths are indispensable elements for manufacturing various weaponry equipment such as precision guided weapons called "smart bombs", radars, and night vision goggles. Because of its low natural abundance and the symbiotic form of oxide or oxysalt minerals, it is called "rare earth".
