Aluminium jumps after Australian ban on alumina exports to Russia

Aluminium jumped at the open in London after Rio Tinto Group moved to halt alumina shipments to Russia, another threat to global supply of the so-called everywhere metal that will also fan global inflation.

The metal rose as much as 4.8% on the London Metal Exchange and was trading up 4.1% at $3 519 a ton as of 9:47 a.m. in Shanghai. Used in everything from cans to window frames, aluminium has risen around 25% this year.
