Extracting the truth about rare earths | INTHEBLACK

Actually, rare earths are not particularly rare. According to mining.com, the least abundant rare earth elements – thulium and lutetium – are still almost 200 times more common than gold. Plus, they are often required only in small amounts, leading to them being referred to by some as the vitamins of the minerals industry.
