Making Aluminum

Aluminum is a relatively abundant element in the earth's crust. Minerals are a commercial source of aluminum is bauxite. Bauxite contains aluminum in the form of aluminum oxide (Al2O3). Processing of aluminum into pure aluminum can be done through two steps: 1. Bauxite refining stage in order to obtain pure aluminum oxide (alumina) 2. Phase smelting alumina Bauxite refining stage is to eliminate the major impurities in bauxite. The main impurities of bauxite typically consist of SiO2, Fe2O3, and...
