Aluminum industry in the United States - Wikipedia
The aluminum industry in the United States in 2023 produced 860 thousand metric tons of aluminum from refined metal ore (primary production), at six smelters. In addition, US industry recycled 3.4 million tons of aluminum (so-called secondary production aluminum). [ 1 ]
Aluminium - Wikipedia
Aluminium is found on Earth primarily in rocks in the crust, where it is the third-most abundant element, after oxygen and silicon, rather than in the mantle, and virtually never as the free metal. It is obtained industrially by mining bauxite, a sedimentary rock rich in aluminium minerals.
Aluminum Production and Processing
Primary production involves mining bauxite deposits from the earth, chemically refining it into pure aluminum oxide and performing electrometallurgical processing to ultimately form aluminum. Secondary production makes new aluminum from recycled scrap that for many products, like cans, is completely suitable for the same high quality.
Primary Production 101 - The Aluminum Association
Primary production is the process by which alumina is smelted to pure aluminum metal. The Hall–Héroult process, simultaneously discovered in 1886 by American Charles Martin Hall and Frenchman Paul Héroult, continues as the main industrial process by which primary aluminum is …
