uses of bauxite ore
Bauxite
Bauxite (Fig. 1.33) is formed by surface weathering of clay rocks around the tropical region and composer of aluminum oxide (Al(OH) 3). It contains 15%–25% aluminum and only ore used for commercial extraction for aluminum. The bauxite occurs as near-surface layers and usually mixed with clay minerals, iron oxide, and titanium dioxide.

Aluminum facts
Aluminum does not exist in a pure state in nature. 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. It takes approximately 4 to 5 tonnes of bauxite ore to produce 2 tonnes of alumina.

Extraction of Aluminium from Bauxite by Bayer's & Hall's Process
Ans: Leaching is done to concentrate pure alumina from bauxite ore. This is done by Bayer’s process in which bauxite is treated with caustic soda followed by heating and calcinating aluminium hydroxide. Q.2. Why is cryolite used in the extraction of aluminium? Ans: Pure alumina has a very high melting point of \(2072\) degree Celsius.
