Rare Metals
The following metals are commonly defined as “rare”, whereby annual production is, on the whole, 25,000 metric tonnes or less. Only the most obscure of these rare metals, such as the rare earths holmium, ytterbium, and lutetium, can still be defined as minor metals: this is because even today they only have minor uses since they are (and will remain) too rare ever to be available in sufficient quantity for mass production.
