  • 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 postmining rehabilitation, efficient recycling, and generally reducing our consumption

  • Extraction Process of Aluminium from Bauxite Ore

    Aluminum is the most abundant metal in the earth’s crust and is a constituent of many minerals However, the material which is highest in aluminum and most free from objectionable impurities is bauxite which, therefore, is practically the only source of the metal under present processes Bauxite is the general name given to the hydrated oxides of aluminum

  • Mining and Refining – Process World Aluminium

    Bauxite is generally extracted by open cast mining, being almost always found near the surface, with processes that vary slightly depending on the location Before mining can commence the land needs to be cleared of timber and vegetation Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of postmining
