medium Q4 of 15
Step-by-Step Solution
Step 1: Understand extraction methods of metals
Aluminium is extracted by electrolysis of molten alumina (bauxite ore).Step 2: Compare with other metals
Iron is extracted by reduction with carbon; zinc and copper are extracted by roasting and reduction, not electrolysis.Final Answer:
Aluminium → Option CQuick Check:
Electrolytic extraction metal = Aluminium ✅
Quick Trick: Remember Hall-Héroult process is for aluminium extraction.
Common Mistakes:
- Confusing iron or copper extraction methods with electrolysis.
