Production. In nature, aluminum does not exist in a pure state. The production of primary aluminum metal begins with bauxite ore, which is composed of hydrated aluminum oxide (40% to 60%) mixed with silica and iron oxide.
Iron and Aluminium are different metals that exhibit varying properties. Both the metals '" Iron and Aluminium come with different molecular mass, atomic weight and atomic numbers. They also come up with difference in the chemical and physical properties. One of the first differences that one

Bauxite is primarily comprised of aluminum oxide compounds (alumina), silica, iron oxides and titanium dioxide. Approximately 70 percent of the world's bauxite production is refined through the Bayer chemical process into alumina. Alumina is then refined into pure aluminum metal through the Hall–Héroult electrolytic process.

Aluminum. Aluminum is the most abundant metal element in the Earth's crust. Bauxite ore is the main source of aluminum and contains the aluminum minerals gibbsite, boehmite, and diaspore.
Silicon alloys include a variety of metals, including iron, aluminum, copper, nickel, manganese and ferrochromium. Relation to Mining In almost all cases, silica mining uses open pit or dredging mining methods with standard mining equipment.
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
