Bauxite is the ore for which metal?

Bauxite is the ore for which metal?

• A. Copper
• B. Zinc
• C. Iron
• D. Aluminum

Answer: (D)

Bauxite is the ore from which aluminium is obtained. It contains aluminium hydroxide minerals (gibbsite, boehmite, and diaspore) along with impurities. The extraction sequence starts with the Bayer process, which refines bauxite to produce alumina (aluminium oxide), and then the Hall-Héroult process, which reduces alumina to pure aluminium metal. This is why bauxite is associated with aluminum rather than copper, zinc, or iron, whose ores are different minerals (copper ores like chalcopyrite, zinc ores like sphalerite, iron ores like hematite or magnetite).
