Chapter 11 Raw materials for aluminium …

Raw materials for aluminium production Example 11.1 A refiner has to produce an aluminium alloy with a maximum of 150 ppm Cr. The already purchased scrap contains 200 ppm Cr. Primary aluminium (price 1~50 ~//t) with 1 ppm Cr and wrought alloy scrap with 20 ppm Cr (price 1200 ~//t) are available. Which offers the most economic blend?

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.

Asteroid mining - Wikipedia

Asteroid mining is the exploitation of raw materials from asteroids and other minor planets, including near-Earth objects.. Hard rock minerals could be mined from an asteroid or a spent comet. Precious metals such as gold, silver, and platinum group metals could be transported back to Earth, while iron group metals and other common ones could be used for construction in space.

Aluminium | Geoscience Australia

Aluminium can be extracted (uneconomically) from some clays but the most common aluminium ore is a material called bauxite. First the aluminium ore needs to be mined, then the bauxite is refined into alumina (aluminium oxide). Large amounts of electricity are used to smelt the alumina into aluminium metal. Properties
