• Aluminium Geoscience Australia

    IntroductionPropertiesUsesHistoryFormationResourcesMiningProcessingAluminium is all around you—from everyday items such as a soft drink can to the aircraft flying overhead. Aluminium is one of the most useful materials known to man. It can be alloyed (mixed) with almost any other metal to create materials with useful properties. Metals alloyed with aluminium are all very strong yet lightweight, and resistant to rusting. After oxygen and silicon, aluminium is the third most abundant element in the Earth's crust (8.2%) and by far the most plentiful metal. Unlike metals such as copper, g

    Aluminum processing Aluminum processing Ores: Aluminum is the third most abundant element on Earth’s surface. Only oxygen and silicon are more common. Earth’s crust to a depth of 16 km (10 miles) contains 8 percent aluminum. Aluminum has a strong tendency to combine with other common elements and so rarely occurs in nature in the metallic form.

  • Alumina Limited

    Aluminium ore, most commonly bauxite, is plentiful and occurs mainly in tropical and sub-tropical areas Africa, West Indies, South America and Australia with some deposits in Europe. Although plentiful, bauxite quality is diminishing, is often not readily accessible and is becoming harder to gain approvals for expansions or new mines.

  • How Aluminium is Made The Australian Aluminium Council

    Bauxite is the primary ore from which aluminium metal is extracted. Australia has the second largest reserves of bauxite in the world and is currently the world’s largest producer (102 Mt in 2019). Once the bauxite is mined from the surface, the land is rehabilitated.

    Unlike its complex origins, the recycling of aluminum requires comparatively less processing; aluminum is broken down into shredded scrap, processed in a decoating kiln to remove any coatings or lacquers, and then melted and cast into ingots, ready for reuse. Conclusion. The journey from bauxite ore to aluminum is complex.
