Aluminium price hits 13-year high - mining-technology

2021-10-12  The price of aluminium has reached a 13-year high due to the deepening energy crisis, which has squeezed supplies of the metal. Aluminium rose as much as 2.8%, to $3,049 a ton, on the London Metal Exchange on Monday, the highest since July 2008, leading to broad gains among base metals. A major cause of this price hike is the energy-intensive ...
