NALCO Angul smelter: an aluminum operation in India
NALCO Angul smelter is an aluminum smelter producing aluminum in Angul, India, operated by NALCO. The sources report 4.72 lakh tonnes (LT; 1 lakh = 100,000) for FY2025-26 (1 April 2025 to 31 March 2026); the basis is Whole smelter (NALCO's company figure for cast metal). The sources do not give a whole-operation figure in primary aluminum that can be compared with world output, so no share is computed.

How much does it produce?
| Period | Output | Basis | Where in the source |
|---|---|---|---|
| FY2025-26 (1 April 2025 to 31 March 2026) | 4.72 lakh tonnes (LT; 1 lakh = 100,000) | Whole smelter (NALCO's company figure for cast metal) | PDF p.10 (printed slide 9), 'Physical Performance FY 2025-26', row 'Cast Metal: 4.72 LT' · National Aluminium Company Limited |
Status: operating, as of 31 March 2026.
- The figure is printed to two decimals in lakh tonnes, so it is precise to about 500 tonnes. It is cast metal as defined by NALCO, which the presentation does not further define.
- The fiscal year ends on 31 March, so the period overlaps CY2025 for nine months only.
- Cast metal is casthouse output and the presentation does not define it as primary smelter production, so no share of world output is computed.

Method and limits
- Reported, not estimated. Output is the figure the operator or owner published, in the unit it used. This site does not estimate output where none is published.
- Shares. A share divides output in primary aluminum by the USGS world or country total for 2025. Where the operator's year is a fiscal year or the unit is a concentrate or a carbonate equivalent, the share is approximate or not given.
- What is compared. The figure is tonnes of primary aluminum metal produced by the whole smelter, compared with USGS smelter production of primary aluminum. Remelted and recycled metal is not primary production.
- Whole operation or owner's share. The basis column says which. A joint venture's output is never counted twice.
- Partial list. Only operations with a published figure are listed, so the rank is among those on this site, not among every aluminum mine. Shares of a country's output mix periods and bases, so treat them as indicative.
