Relation to Mining. Because aluminum metal reacts with water and air to form powdery oxides and hydroxides, aluminum metal is never found in nature. Many common minerals, including feldspars, contain aluminum, but extracting the metal from most minerals is very energy-intensive, and expensive. Therefore, bauxite is the primary source of the ...

In nature, aluminum does not exist in a pure state. The production of primary aluminum metal begins with bauxite ore, which is composed of hydrated aluminum oxide (40% to 60%) mixed with silica and iron oxide. It takes approximately 4 to 5 tonnes of bauxite ore to produce 2 tonnes of alumina.
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 ...

Aluminum must be refined from ore Although aluminum is the most common metal found on Earth (totaling 8 percent of the planet's crust), the metal is too reactive with other elements to occur naturally. Bauxite ore, refined through two processes, is the primary source of aluminum. Land conservation is a key industry focus
Acid mine drainage (AMD) has degraded water quality and ecology in streams on the Stockton Plateau, the site of New Zealand's largest open-cast coal mining operation. This has previously been attributed largely to the effects of acidity and elevated aluminium (Al) concentrations.
Transforming alumina -- aluminum oxide -- into aluminum represented a major milestone in the industrial revolution. Until modern smelting techniques evolved, only small quantities of aluminum could be obtained. Most early processes relied on displacing aluminum with more reactive metals, but the metal remained expensive and relatively elusive.

For centuries, that's all aluminum was good for, until in 1825 AD the Danish chemist Hans Orsted managed to create a lump of aluminum metal. In the 1850s, pure aluminum was so difficult to produce that bars of it were more valuable than gold and even exhibited as a curiosity at the Exposition Universelle in 1855.
The aluminum industry in the United States in 2014 produced 1.72 million metric tons of primary aluminum, worth 3.97 billion dollars, at nine aluminum smelters. In addition, the US produced 1.70 million tons of secondary aluminum from old (post-consumer) scrap, and 1.93 million tons of aluminum from new (manufacturing) scrap.
