This isn\’t correct at all:
Alumina, the ore from which aluminium is extracted, is not rare. In fact, it makes up about 6pc of the world\’s crust.
The ore is bauxite. Which you then convert to alumina using the Bayer Process.
OK, so you might not worry all that much about such a mistake in a general news column, but in a commodities column, trying to explain the secrets of the aluminium trade?
