Aluminium Dunkerque has installed its first aluminium purifier at its foundry, as part of the company’s Crystal Project.
The purifier, operated in collaboration with Dynamic Concept, will allow the company to produce high-purity aluminium by lowering the content of chemical elements other than aluminium in the liquid metal resulting from the electrolysis process.
The metal that comes out of the tanks is composed of 99.7% aluminium, the objective is to achieve a purity of at least 99.98%.
This segregation process requires advanced technologies for proper purification control. It separates the chemical elements to concentrate the impure elements (silicon, iron, copper, manganese, magnesium, etc.) to discard them and keep only pure aluminium.
This pure aluminium is mainly used in microelectronics and vehicle batteries, markets that are currently experiencing significant growth in the context of digital technology and electric mobility.
The purifier will come into operation in 2026. As soon as the company achieves the desired purity and obtained the approvals, the high-purity plant will be built by 2028/2029.
This promising project will bring back to France a production that has mainly been based in China, Russia and Norway.
