Qatalum smelter: an aluminum operation in Qatar

Qatalum smelter is an aluminum smelter producing aluminum in Qatar. The sources report 324 '000 tonnes (kt) of primary aluminum ('Primary aluminium production (kmt)'), Hydro's 50% share for CY2025; the basis is Hydro's 50% share (footnote 1: part-owned companies are shown at Hydro's proportional share). Measured as primary aluminum, whole-operation output for CY2025 is about 648,000 tonnes (derived here, not printed by the source): about 0.9% of world aluminum output in 2025; it is one of 28 operations on this site whose output can be stated in primary aluminum.

How much does it produce?

Reported output of Qatalum smelter
Period	Output	Basis	Where in the source
CY2025	324 '000 tonnes (kt) of primary aluminum ('Primary aluminium production (kmt)'), Hydro's 50% share The same row prints electrolysis capacity of 324 thousand tonnes and casthouse production of 344 thousand tonnes (both Hydro's share).	Hydro's 50% share (footnote 1: part-owned companies are shown at Hydro's proportional share)	PDF p.302 (printed p.302), table 'Production capacity Hydro Aluminium Metal', row 'Qatalum (50%)', column 'Primary aluminium production (kmt)' · Norsk Hydro ASA

How the primary-aluminum figure is worked out. Hydro prints 324 thousand tonnes as its 50% share of primary aluminum production at Qatalum in 2025; the 50% interest is printed on the same row and on PDF p.168. 324 / 0.50 = 648 thousand tonnes, which is 648,000 tonnes for the whole smelter. World smelter production of primary aluminum in 2025 was 74,000,000 tonnes (USGS Mineral Commodity Summaries 2026).

Status: operating, as of 30 September 2026.

Hydro's third quarter 2026 report says the plant operates at around 60 percent of its capacity. This 2026 event does not affect the 2025 figure.

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.
