Explanation
Aluminium plants and their locations
| Company | Plant location | State |
|---|---|---|
| A. BALCO (Bharat Aluminium Co.) | 2. Korba | Chhattisgarh |
| B. HINDALCO | 4. Renukoot | Uttar Pradesh |
| C. Indian Aluminium Co. (INDAL) | 1. Hirakud | Odisha |
| D. NALCO | 3. Koraput (Damanjodi mines/refinery) | Odisha |
NALCO's smelter is at Angul, while its bauxite mine and alumina refinery are at Damanjodi, Koraput.
Renukoot was chosen for cheap power from the Rihand Dam.
Answer: (b) A-2, B-4, C-1, D-3.
Why each option is right or wrong
- (a) Incorrect. BALCO is at Korba, not Koraput.
- (b) CORRECT. BALCO-Korba, HINDALCO-Renukoot, INDAL-Hirakud, NALCO-Koraput.
- (c) Incorrect. BALCO is not at Koraput, and NALCO is not at Korba.
- (d) Incorrect. HINDALCO is at Renukoot, not Hirakud.
Key point
BALCO-Korba (CG); HINDALCO-Renukoot (UP); INDAL-Hirakud (Odisha); NALCO-Koraput/Damanjodi + Angul (Odisha).
Remember
BALCO is at Korba; NALCO is at Koraput.
Common mistakes
- Confusing Korba and Koraput — the names sound alike.
- Forgetting that aluminium plants sit near cheap hydro-power (Rihand → Renukoot, Hirakud).
- Thinking NALCO has only one site — mine/refinery at Damanjodi, smelter at Angul.
Exam tip
Korba = BALCO (B for both 'Bharat' and 'Korba-B'); Koraput = NALCO. Hindalco → Hydro (Rihand) → Renukoot.
