Yttrium never occurs in nature as a free element. It is found in almost all rare earth minerals and in uranium ores. The yellow-brown ore xenotime can contain as much as 50% yttrium phophate (YPO4) and is mined in Malaysia.
The story of yttriumâs discovery begins in 1787, when Carl Arrhenius found a coal-like mineral in a feldspar/quartz mine near Ytterby, Sweden. The mine had been developed in the early 18th century as a result of the mineral requirements of the local pottery industry.
