    Energy needed to produce aluminum - Today in Energy - U.S

      Because smelting requires significant amounts of electricity, some primary aluminum smelters can be found in areas with lower-cost electricity, often in areas with rich hydroelectric resources, such as the Pacific Northwest and Upstate New York. However, other smelting plants can be found in the Midwest, Appalachia, and Texas.

    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.

    Although the United States has the vast coal resource described in the previous chapter, perhaps as much as 4 trillion tons, the key issue for policy makers is the amount of coal that is economically recoverable.This is not a fixed quantity, but depends on the geological resource, the market price, and the cost of mining. The particular characteristics of the coal mining industry create unique

    Basics of an open pit mine

    Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.

    Mining industry and sustainable development: time for change

    Mining industries provide many of the raw materials for equipment we use daily, from aluminum cans up to electronic chips of cell phones and computers. To arrive here, metal mining steadily increased over the centuries, with occasional “rushes” for several minerals (silver, gold, radium, etc.) which occurred in connection with booms in demand.

    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 post-mining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.
