Which one of the following industries uses bauxite as a raw material?

(a) Aluminium Smelting

(b) Cement

(c) Paper

(d) Steel

Answer:

(a) Aluminium Smelting ✅

Explanation:

• Bauxite is the primary ore of aluminium and is used in the aluminium smelting industry to extract pure aluminium metal.
• The extraction process involves refining bauxite into alumina (Al₂O₃), which is then subjected to electrolysis to produce aluminium.
• Aluminium is widely used in industries such as transportation, construction, electrical wiring, and packaging due to its lightweight and corrosion-resistant properties.

Thus, the aluminium smelting industry is the correct answer. 🚀🔧
