Mining has a large impact on the environment because minerals are contained within the Earth. Earth must be removed in order to extract the minerals. When the minerals are close to the surface, the earth is removed, causing destruction to the shape of the land and the flora and fauna living in that area.

Primary aluminum production begins with the mining of bauxite ore, a hydrated oxide of aluminum consisting of 30 to 56 percent alumina (A l2O3) and lesser amounts of iron, silicon, and titanium. The ore is refined into alumina by the Bayer process. The alumina is then shipped to a primary aluminum plant for electrolytic reduction to aluminum.

Bauxite Mining. Aluminium is the third most abundant element in the Earth's crust, but does not occur as a metal naturally. The first step in producing aluminium is mining its ore – occurs mainly in tropical and subtropical areas, like Africa, the West Indies, South America and Australia – there are some small deposits ...

Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat. ...

Bauxite mining in the United States produced an estimated 128,000 metric tonnes of bauxite in 2013. Although the United States was an important source of bauxite in the early 20th century, it now supplies less than one percent of world bauxite production.

Recycling aluminum saves 90% to 95% of the energy needed to make aluminum from bauxite ore. It doesn't matter if you're making aluminum cans, roof gutters or cookware, it is simply much more energyefficient to recycle existing aluminum to create the aluminum needed for new products than it is to make aluminum from natural resources.

Ninetyfive percent of all beer and soft drink cans in the United States are made of aluminum. American can makers produce about 100 billion aluminum beverage cans a year, equivalent to one can per American per day. While almost all food cans are made of steel, aluminum's unique properties make it ...
