Chapter 2. Production and Processing of Aluminum
The starting material for electrolytic smelting of aluminum is pure, anhydrous alumi-num oxide (Al 2 O 3) called alumina. In the Western World, the Bayer 1 process, invented in the 19th century, is by far the most important process used in the production of alumi-num oxide from bauxite. The process has been refined and improved since its inception.

How is Aluminum Recycled? Step by Step | Greentumble
Aluminum recycling process. The process of recycling aluminum is tremendously efficient. Only five percent of the energy invested in creating fresh supplies of aluminum is required to recycle the same amount, and because aluminum is infinitely reusable there is no loss of quality once the recycling process is finished [4].. Briefly, here's how the aluminum recycling process works [5]:

Sorting technology can turn aluminum green - Recycling Today
Recycling aluminum has the potential to produce 92 percent fewer CO 2 emissions than new aluminum. In 2019, 20 million metric tons of aluminum was recycled globally, which is an equivalent saving of 300 million metric tons of greenhouse gases. Processing 1 metric ton of aluminum scrap also saves 8 metric tons of bauxite from having to be mined.

As stated, an aluminum chip is a drop of aluminum surrounded by an oxide layer. When chips are compressed, all the oxide layers are compressed inside the puck/briquette (Figure 5). As the material is melted, all these oxide layers will grow. In addition, molten aluminum is 15% less dense than solid aluminum.

Aluminum develops an oxide layer to fully protect against corrosion. This "oxide skin" makes the metal resistant not only to weathering, but also to many (not all) acids. Aluminum is also considered "easy" to machine. CNC machines and aluminum are compatible because the metal is pliable, so it chips easily.
