  • 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

  • Aluminium mineral extraction– open pit, surface mining

    Aluminium is mined from bauxite-contained mining areas since the production of aluminium is entirely reliable on extraction from bauxite. It is not found in free form and is the most abundant metallic element in the Earth’s crust. Bauxite is the only ore containing 20-25 percent of aluminium from where the metal is extracted and commercially produced. The open pit or surface mining process

  • How Aluminum Works | HowStuffWorks

    2008-09-29· ­After th­e ore is discovered, open-pit mines typically provide the bauxite that will eventually become aluminum. First bulldozers clear land above a depos­it. Then workers loosen the soil with explosives, which bring the ore to the surface. Giant shovels then scoop up the bauxite-rich soil and dump it into trucks, which carry the ore to a processing plant. ­

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

    Aluminum (or Aluminium, if you’re not from the US) is an abundant element within Earth’s surface— but getting it out of the ground is an arduous process, requiring heavy machinery to plow up acres and acres of land. Fortunately, the environmental impact of that process can be somewhat balanced out by post-mining rehabilitation, efficient recycling, and generally reducing our consumption.

    Bauxite mining in the United States produced an estimated 128,000 metric tonnes of bauxite in 2013. Bauxite is the only commercial ore of aluminium, and 96 percent of bauxite consumed in the US is used to produce aluminum (metallurgical grade). However, since 1981, none of the bauxite mined in the US was used to make metallic aluminium. US bauxite is instead used for abrasives, high
