Why Should We Recycle Aluminum?

Jul 24, 2019The opposite of saving energy is wasting it. 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 100-watt incandescent light bulb burning for five hours or to power the average laptop computer for 11 hours, according to the Container Recycling Institute.

THE EXTRACTION OF METALS

Aluminium, for example, is the most common metal in the Earth's crust, occurring in all sorts of minerals. However, it isn't economically worthwhile to extract it from most of these minerals. Instead, the usual ore of aluminium is bauxite - which contains from 50 - 70% of aluminium oxide.

Bauxite

Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH)3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite and haematite, the aluminium clay mineral kaolinite and small amounts of anatase (TiO2) and ilmenite (FeTiO3 or FeO.TiO2).

The Properties, Production, and Applications of Tin

Dec 17, 2018Tin is a soft, silvery-white metal that is very light and easy to melt. Being so soft, tin is rarely used as a pure metal; instead, it is combined with other metals in order to make alloys that possess tin's numerous beneficial properties. These include a low toxicity level and a high resistance to corrosion.Tin is also both malleable (easy to press and shape without breaking) and ductile

Mining and Refining

Alumina is used for the production of aluminium metal, through the Hall–Hroult electrochemical smelting process. The Bayer Process is the most economic means of obtaining alumina from bauxite. Other processes for obtaining alumina from metal ores are also in use in some refineries, particularly in China and Russia, although these make up a relatively small percentage of global production.
