Today's aluminium is produced via two main methods:, primary aluminium production from ore or recycling aluminium from processing scrap and used aluminium products.
To fulfil the need of the customer, Heraeus Electro-Nite offers solutions specific for the Primary Aluminium process.
The process of an integrated primary aluminium production consists of bauxite mining, alumina production and reduction of alumina into liquid aluminium via electrolysis.
Find out which solutions are applicable for your process and how they can help you to optimize your Primary Aluminium process.
The electrolytic reduction is the final step in the primary aluminium production process. This step takes place in the reduction plants or smelters.
Aquí se extrae aluminio puro de alúmina mediante el proceso Hall-Héroult. La alúmina se vierte en celdas electrolíticas con un baño de criolita fundida a unos 950 grados Celsius. Aplicando una corriente eléctrica de alta intensidad, se obliga a romper la conexión entre el aluminio y los átomos de oxígeno, lo que hace que el aluminio líquido caiga al fondo de la celda electrolítica.
Un funcionamiento estable de la celda es clave para lograr una operación de reducción de costes eficiente.
