Aluminum Statistics and Information
Aluminum recovery from scrap (recycling) has become an important component of the aluminum industry. A common practice since the early 1900s, aluminum recycling is not new. It was, however, a lowprofile activity until the late 1960s when recycling of aluminum beverage cans finally vaulted recycling into the public consciousness. Sources for recycled aluminum include automobiles, .
Extraction of Aluminium by Electrolysis
Aluminum oxide, however, has a high melting point. Therefore, aluminum oxide is dissolved in molten cryolite. Cryolite is a form of an aluminum compound that has a lower melting point that aluminum oxide. The steel case, used in electrolysis, is coated by graphite. Graphite is a form of carbon and acts at the negative hode. The positive anodes are also made of graphite but are immersed in ...

Will We Need To Mine Metals In The Future? | Wood Mackenzie
· Environmental policy will force a rapid increase in scrap utilisation. By 2040, an extreme environmental regulation scenario equivalent to our AET2, or 2 °C world scenario, would reduce primary metal demand by up to 35% for iron, 47% for aluminium and 34% for copper. This could prove truly transformative for producers and the planet alike.

Aluminium
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and ...
Aluminium Recycling – Home
Aluminium recycling saves over 90 million tonnes of CO 2 annually. Recycling avoids the direct greenhouse gas emissions associated with primary aluminium production and up to 95% of the energyrelated emissions. Emissions savings from aluminium recycling have more than doubled since 1990 and are projected to increase by a further 50% by 2020. Annual CO 2 Savings from Recycling Aluminium ...
Primary Production | The Aluminum Association
Primary production is the process through which new aluminum is made (versus secondary production, in which existing aluminum is recycled into pure metal). Aluminum originates from bauxite, an ore typically found in the topsoil of various tropical and subtropical regions. Once mined, aluminum within the bauxite ore is chemically extracted into alumina, an aluminum oxide compound, through the ...
