    Primary production starts with bauxite ore, which, in the United States, is usually imported from Jamaica and South America. Bauxite is then converted into aluminum oxide, or alumina, using natural gas at plants located in the southern United States.

  • Aluminum industry in the United States - Wikipedia

    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.

    For example, the United States imports bauxite (an aluminum ore) and produces aluminum metal. NIR for bauxite exceeds 75%, but NIR for aluminum is 61%. Lack of By-Product Recovery

  • How Aluminum is Produced

    Aluminum is formed at about 900°C, but once formed has a melting point of only 660°C. In some smelters this spare heat is used to melt recycled metal, which is then blended with the new metal. Recycled metal requires only 5 per cent of the energy required to make new metal .

  • Mining and Refining – Process - World Aluminium

    Aluminium is the most abundant metal in the earth's crust. The aluminium-containing bauxite ores gibbsite, böhmite and diaspore are the basic raw material for primary aluminium production. Proven, economically viable reserves of bauxite are sufficient to supply at .

    Aluminum - The ore is mined from rocks that have been exposed to weathering in a tropical environment, bauxite. The main ore minerals in bauxite are gibbsite, bohmeite, and diaspore. Antimony - The primary ore of antimony is it's sulfide, stibnite.

  • 12.1 Primary Aluminum Production - US EPA

    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.
