The Benefits of Aluminum Recycling ThoughtCo

Toss an aluminum can into the trash instead of recycling it, and the energy required to replace that discarded resource with new aluminum from bauxite ore is enough to keep a 100watt incandescent light bulb burning for five hours or to power the average laptop computer for 11 hours, according to the Container Recycling Institute.

Copper Vs. Aluminum Windings in Motors ACHR News

Jan 18, 2001· The great debate of copper vs. aluminum windings in motors is still going on. It's a topic that I first wrote about in 1988, and it remains a topic of discussion today as engineers in a variety of industries question whether the quality and performance of aluminum windings can possibly compare with copper.

How aluminium is produced All About Aluminium

Aluminium atoms easily bind with other metals, forming compounds. At the same time it's impossible to isolate aluminium by simply melting down the compounds in a furnace, as is the case with iron, for example. The aluminium production process is much more complex and requires huge amounts of .

Types of Extraction | Scool, the revision website

Methods of extraction Many metals are found in the Earth's crust as ores. An ore is usually a compound of the metal mixed with impurities. When the metal is dug up, a method must be used to separate the metal from the rest of the ore. This is called extracting the metal. The method of extraction depends on how reactive the metal is. The more reactive the metal, the more difficult it is to ...
