Aluminum
Hello buddy! How is the weather in Paris? It is extremely cold in New York and there is snow all over the place. The reason I am writing is to give you the information you wanted on aluminum. I have everything you would possibly want to know about everything from mining to recycling, but I will begin with a little background on the element first. Aluminum is the third most abundant element in the Earth's crust and was probably formed during the birth of our solar system through collisions of hydrogen atoms under intense heat and pressure. Aluminum never occurs as a metal in nature and is only found in the form of its compounds, such as alumina, because of its strong affinity with oxygen. It is this special bond for oxygen that explains why it withstood all attempts to prepare it in its elemental form until well into the nineteenth century. The aluminum industry was founded in 1854, but it was not until the late 1880's that a method was found to bring down the prices and permit aluminum to be used in a wide variety of ways. Most of the aluminum in the world today is made from Bauxite. It was first discovered in 1821 near Les Baux, France. It was formed by the weathering of aluminous r
Most of these large Bauxite deposits are found in the tropical and the subtropical climates, where heavy rainfall, warm temperatures, and good drainage combine to encourage the weathering process. Production of Aluminum and Alumina, (1987). Xavier, I hope I gave you a little more information then you already had. They can make your job easier by keeping the cans in separate containers until you can pick them up. In these tanks, which are injected with steam, the alumina is turned into a creamy slurry and poured into a settling tank. This process begins when bauxite is smashed by being mixed with soda ash and lime in a ball mill. Aluminum also has the highest strength to weight ratio of any of the commercial metals. Try to pass out other information about your project at local supermarkets and other high visibility areas to help promote the program. Aluminum is increasingly used to conserve energy both in home heating and cooling.
