    Bauxite - Wikipedia

    Australia is the largest producer of bauxite, followed by China. In 2017, China was the top producer of aluminium with almost half of the world's production, followed by Russia, Canada, and India. Although aluminium demand is rapidly increasing, known reserves of its bauxite ore are sufficient to meet the worldwide demands for aluminium for many centuries.

    Mining and Refining Responsible Sourcing

    Bauxite mining consumes a relatively small amount of energy (and consequently has low greenhouse gas emissions) compared to alumina refining and aluminium smelting processes. Diesel fuel and fuel oil combustion provides the bulk (95%) of the energy required to extract and haul the mined ore.

    Aluminium recycling - Wikipedia

    Aluminium recycling is the process by which scrap aluminium can be reused in products after its initial production. The process involves simply re-melting the metal, which is far less expensive and energy-intensive than creating new aluminium through the electrolysis of aluminium oxide (Al 2 O 3), which must first be mined from bauxite ore and then refined using the Bayer process.
