What Is Aluminum Smelting? (with picture) - wisegeek.com

Oct 03, 2018· Aluminum smelting is an industrial process used to produce metal. The manner in which this is done depends on whether the aluminum is being produced by way of a primary process, involving bauxite, or a secondary process, involving scrap. The primary process is the most complex and energy intensive.
