Comment est fabriqué l'Aluminium ? (De la Roche au Métal Énergivore)

Aluminum is everywhere around us: in our planes, our phones, our cars... But do you know how this essential metal is made? It's one of the most complex and energy-intensive industrial processes in the world! To produce one ton of aluminum, it takes as much electricity as a house consumes in a year! In this video, dive into the heart of the factories to discover the fascinating process of aluminum manufacturing. It all starts with bauxite, a rock extracted from the earth. You'll see how this rock is transformed into an ultra-pure white powder called alumina, using the Bayer process, which involves heat (up to 200°C) and chemistry. The real magic (and the secret to the enormous electricity consumption) happens next: electrolysis! Discover how alumina is dissolved in a molten bath at 950°C and how a colossal electric current (15 MWh per ton!) transforms it into pure aluminum metal. We'll also explore the purification steps to obtain aluminum with a purity of over 99%, and the different casting methods to give it its final form, ready to become an aircraft part or an electronic component. Get ready for a journey to the heart of a power, chemical, and electrical industry! It's another side of "Titans of Industry"!
