Mining and Refining Aluminum HowStuffWorks

CompositionGeologyProductionUsesAluminum isn't found in nature as a pure element. It exhibits relatively high chemical reactivity, which means it tends to bond with other elements to form compounds. More than 270 minerals in Earth's rocks and soils contain aluminum compounds. This makes aluminum the most abundant metal and the third most abundant element in Earth's crust. Only silicon and oxygen are more common than aluminum. The next most common met在science.howstuffworks上查看更多信息

aluminum processing History, Mining, Refining,Facts

Aluminum, or aluminium (Al), is a silvery white metal with a melting point of 660 °C (1,220 °F) and a density of 2.7 grams per cubic cm. The most abundant metallic element, it constitutes 8.1 percent of Earth’s crust. In nature it occurs chemically combined with oxygen and other elements. In the pure state it is soft and ductile, but it can be alloyed with many other elements to increase

Mining and Refining Energy Efficiency World Aluminium

Aluminium is an “energy bank”; most of the original input can be recovered every time the product is recycled. Bauxite mining requires relatively low energy inputs, compared to other steps in the aluminium production process with less than 1.5 kilograms of fuel oil (mainly in the form of diesel for haul trucks) and less than 5 kWh of

The Environmental Impact of Aluminum (And Why it’s Still

If refining aluminum sounds incredibly resource-intensive, that’s because it is. Extractive industries like mining (for any ore, element, oil, or gem) are not our most earth-friendly activity. Refining takes a lot of energy, as well. It’s hard to live in our modern world without extraction, so
