Answer: Rare earth metals

The fifteen lanthanides (elements named after one of them, lanthanum, which all have similar properties) together with the elements scandium and yttrium make up the group of metals called the "rare earths". In fact they are not particularly rare in nature (except for the radioactive promethium), but they are thinly distributed. Often several of them occur in the same mineral which makes it difficult to separate them out.

Many of them have important industrial uses.
