recycled aluminum oxide

Aluminum Recycling - American Chemical Society

Aluminum is extracted from an ore known as bauxite, which consists of aluminum oxide (Al 2 O 3) and other compounds that contain aluminum, silicon, titanium, and iron. Aluminum oxide is separated from the other elements using the Bayer process, which consists of three stages. First, bauxite is dissolved in a solution of sodium hydroxide at high pressure and temperature. The resulting mixture ...

What is Aluminium Recycling? - The Process Uses

First off, it’s more energy-efficient and affordable to recycle this metal instead of creating aluminium. Recycling this metal consists in simply melting it again. Creating new aluminium requires a higher amount of energy and money, because it uses a complex processes which is based on the electrolysis of aluminium oxide.
