Known global reserves can meet total demand for centuries. Western Australia accounts for around 67 per cent of Australia’s alumina production, with the State’s alumina projects among the lowest costs producers in the world. The State’s main producers are Alcoa of Australia and South32’s majority owned Worsley Alumina. Alumina is the State’s third most valuable mineral commodity, accounting for almost 6 per cent of mineral sales value.
WA alumina and bauxite sales volumes have gradually increased year-on-year since 2010–11, reaching a record 14.8 million tonnes in 2017–18. Production is currently focused in the south-west region of the State, with the Darling Scarp containing considerable deposits. Western Australia’s reserves are estimated to be capable of sustaining more than 50 years of alumina production at current levels.
Aluminium foil provides a complete barrier to light, oxygen, moisture and bacteria. For this reason, foil has been used extensively in food packaging since 1911, when Swiss-based Tobler began wrapping its Toblerone chocolate bars in aluminium foil.
Aluminium, which is made via a smelting process that separates alumina into aluminium and oxygen, is the second most widely used metal, after iron. It is widely used in the transport, packaging and electrical systems. Aluminium metal is infinitely recyclable. Without any loss of quality and aluminium scrap it is highly valued.
