    Aluminium,  · Aluminium (in American and Canadian English also: aluminum) is a chemical element. The symbol for aluminium is Al, and its atomic number is 13. Aluminium is the most abundant metal.Why Should We Recycle Aluminum?,  · In addition, every ton of new aluminum cans that must be produced to replace cans that were not recycled requires five tons of bauxite ore, which must be strip-mined, crushed, washed and refined ...3 Ways to Melt Aluminum,  · How to Melt Aluminum. Aluminum is one of the most heavily used metals in modern manufacturing. Its durability and plasticity make it an ideal material for multiple functions. Because of this, aluminum is a great metal for DIY forging. With...How Is Aluminum Extracted From Its Ore?,  · To extract aluminum, the bauxite ore is first crushed, then mixed with lime, hot water and soda ash. This mixture is placed into a digester, where it is heated under steam pressure. Caustic soda is added, which dissolves the alumina from the ore. The other ...An Overview of Municipal Waste and Landfills,  · In addition to landfills, waste can also be disposed of using waste combustors. This involves the burning of municipal waste at extremely high temperatures to reduce waste volume, control bacteria, and sometimes generate electricity. Air pollution from the combustion is sometimes a concern with this type of waste disposal but governments have regulations to reduce pollution..
