Billet Process and Equipment Abstract - ET '22

As the aluminum industry has developed over the past 60 years, the value of the aluminum has increased and the view of the oxidation products (dross) has changed from a material that was sent to the landfill, to a raw feed, completely recycled as valuable downstream products. Aluminum melting generates dross. Dross removal carries out free ...

Aluminium smelting is the process of extracting aluminium from its oxide alumina, generally by the hall-heroult process. Process produces a quantity of fluoride waste: perfluorocarbons and hydrogen fluoride as gases, and sodium and aluminium fluoride and unused cryolite as particulates. Process also produces significant emissions of polycyclic aromatic hydrocarbons as the pitch is baked.
