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.

WE RECYCLE Since 1978 we've been recycling aluminum for re-use in industries across the United States. Aluminum is infinitely recyclable and it takes 95% less energy to recycle than to produce it from raw form. By processing aluminum waste, we have and continue to reduce landfill use and mitigate the effects of mining for this vital resource.
The immense amounts of power required to produce aluminum is the reason why aluminum plants are almost always located in areas where affordable electrical power is readily available. Some experts maintain that one percent of all the energy used in the United States is used in the making of aluminum.
waters draining from these mines are often acidic and contain elevated concentrations of heavy metals (iron, aluminum, and magnesium) and metalloids (arsenic). Active mines are only a minor concern compared to abandoned mines. Active mines may be deep and well below the water table, but pumping water out of the mine or
May 08, 2014· BAUXITE MINING PROCESS AND ASSOCIATED OCCUPATIONAL HEALTH HAZARDS AND RISKS. Although a very small percentage (less than 1% globally) of aluminum is derived from ores such as nepheline and from alternative sources, such as fly ash from coal-fired power stations, bauxite mining represents, by far, the most common initial upstream step in the eventual production of aluminum .
In 2009, Ma'aden established a joint venture with Alcoa, the world's third-largest aluminium producer, to build the world's most efficiently integrated aluminium project in Saudi Arabia. This USD 10.8 billion (over SAR 40 billion) project includes a bauxite mine, a refinery, a smelter and one of the world's most advanced rolling mills.
Once the bauxite is loosened into manageable pieces it is generally loaded into trucks, railroad cars or conveyors and transported to crushing and washing plants or to stockpiles, before being shipped to alumina refineries, which are generally located close to bauxite mines.

11 aluminum cans. 5 hub caps. Vault 81 has upwards of 40 aluminum, mostly in the form of surgical trays, in the secret section of the vault. Federal ration stockpile has roughly 30 aluminum cans on the shelves just outside the locked storage area. Four Leaf fishpacking plant has 24 aluminum trays on the west side of the factory.
90% of the global alumina supply of around 90 million tonnes is used in aluminium production. Alumina refineries tend to be located close to bauxite mines and/or ports for efficient transport of raw materials and of the final product.
In 1995, U.S. plants produced 7.8 billion lb (3.6 million metric tons) of aluminum, and the price of silver was seventy-five times as much as the price of aluminum. Raw Materials Aluminum compounds occur in all types of clay, but the ore that is most useful for producing pure aluminum is bauxite.
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.
Bauxite mining requires relatively low energy inputs, compared to other steps in the aluminium production process – with less than 1.5 kilograms of fuel oil (mainly in the form of diesel for haul trucks) and less than 5 kWh of electricity consumed per tonne of bauxite extracted.
As you have probably noticed, turning Bauxite into Aluminum requires a lot of energy and has a variety of environmental impacts. Both open and underground mines affect the plant and animal life immediately surrounding an area and beyond for multiple generations.

The extraction of aluminum from its ore and subsequent processing into finished prod-ucts takes place in a series of successive operations, each largely independent of the other. Generally the various processes are carried out at different plant sites. A summary of production steps from the bauxite mine through casting is given in Fig. 2.1.
