THE BIG PICTURE: China is the world’s first producer of the Rare earth minerals with its 120 000 metric tonnes annual production. But, due to trade war between Washington and Beijing, the latter has threatened to ban the export of its rare earth ores to the United States in retaliation to the US hiking of tariffs on Chinese goods imported into the US from China.

The principal economic sources of rare earths are the minerals bastnasite, monazite, and loparite and the lateritic ion-adsorption clays. The rare earths are a relatively abundant group of 17 elements composed of scandium, yttrium, and the lanthanides. The elements range in crustal abundance from cerium, the 25th most abundant element of the 78 common elements in the Earth's
