Starting as Bauxite in the earth to becoming the panels on an aircraft, discover how our aluminium is processed and where our metal goes.
In a world with evolving customer demand and a focus on sustainability and durability, aluminium is now - more than ever - the metal of the future. Australia is the world’s fifth largest producer of aluminium, known for global best practice for electricity efficiency and controlling greenhouse emissions during production.
More than 90% of our produce is exported, primarily to southeast Asia, east Asia and India.
We have relationships spanning decades with customers who trust in the quality of our aluminium.
Our metal is custom cast for use in the transport, construction, packaging and electrical industries.
The first step in producing aluminium is mining its ore – bauxite. Mined land is rehabilitated once the
bauxite is extracted from the surface.
Alumina is a white granular material – also called aluminium oxide. Approximately two tonnes of alumina are required for every tonne of aluminium produced.
Smelting is where aluminium is extracted from alumina and cast into products. Like most smelters, Bell Bay Aluminium uses the Hall-Héroult process.
In a large rectangular cell, known as a “pot”, alumina is dissolved in a bath of molten cryolite and other materials.
Carbon blocks, called anodes, are suspended to conduct electricity through the row of pots, called the “potline”.
An electric current flows through the potline, with temperatures of 950°C splitting the alumina into aluminium and oxygen.
At regular intervals, molten aluminium is tapped from the pots and transported to the casthouse.
Aluminium is cast into its final form: at Bell Bay Aluminium, that’s ingot, T-bar and rolling block products.
