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
Try to pass out other information about your project at local supermarkets and other high visibility areas to help promote the program. Take care pal and I will see you very soon. When it is dry, and about 99 percent pure, it is stored in silos, ready for the next process that turns the alumina into aluminum. Aluminum is increasingly used to conserve energy both in home heating and cooling. Aluminum also has the highest strength to weight ratio of any of the commercial metals. Also, aluminum and its alloys are highly resistant to corrosion and are extremely conducive to electricity. Because Bauxite is usually found near the surface, it is mined by open-pit methods. In these tanks, the heavier metals and sand sink to the bottom, while the alumina remains on top. Recycling costs only about five percent of the energy originally used to make aluminum because we eliminate the mining, shipping, refining, and reduction process. Also because vehicle weight is a determinant in gas mileage, aluminum is being substituted for heavier materials. The container packaging industry is by far the biggest user of aluminum, using about thirty percent of the United states production of aluminum, and most of this is in the production of aluminum cans. Wait until you have an abundance of material to bring to the recycling center so you do not waste time and gas and make recycling a little bit more enjoyable for everyone involved. Electricity is then passed through the cryolite to form a crust. 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.
