Paragominas: a bauxite operation in Brazil

Paragominas is an open-pit mine producing bauxite in Paragominas, Para, Brazil, operated by Hydro. The sources report 10,516 kmt (thousand tonnes), wet basis for CY2025; the basis is 100% of the operation (Hydro owns Mineracao Paragominas S.A.). Measured as bauxite, whole-operation output for CY2025 is 10,516,000 tonnes: about 2.4% of world bauxite output in 2025 and about 32% of Brazil's; it is one of 9 operations on this site whose output can be stated in bauxite.

How much does it produce?

Reported output of Paragominas
Period	Output	Basis	Where in the source
CY2025	10,516 kmt (thousand tonnes), wet basis The key-figures footnote states that Paragominas production is on a wet basis. The ESG factbook in the same report prints 10,496 thousand tonnes for 2025 without stating a basis.	100% of the operation (Hydro owns Mineracao Paragominas S.A.)

CY2024	10,506 kmt (thousand tonnes), wet basis	100% of the operation (Hydro owns Mineracao Paragominas S.A.)	PDF p.37, same row, 2024 column · Norsk Hydro ASA

Between CY2024 and CY2025 the reported figure rose by 0.1%, in the same unit and on the same basis.

How the bauxite figure is worked out. Hydro prints bauxite production of 10,516 thousand tonnes for its Paragominas mine in 2025, on a wet basis as footnoted, and owns the mine through a 100% subsidiary, so the figure covers the whole operation. Converted from thousand tonnes to tonnes. World bauxite mine production in 2025 was 440,000,000 tonnes (USGS Mineral Commodity Summaries 2026); Brazil produced 33,000,000 tonnes.

Status: operating, as of 31 December 2025.

The same report prints two 2025 totals, 10,516 thousand tonnes (key figures and country-by-country report) and 10,496 thousand tonnes (ESG factbook table E5.2, PDF p.256). The difference is 20 thousand tonnes and the report does not explain it; the wet-basis figure is used.
Hydro states that about 30 percent of Alunorte's long-term bauxite requirements are covered by supplemental supply from Mineracao Rio do Norte (MRN). Alumina refineries and aluminum smelters are separate from this bauxite mine entry.

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 bauxite 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. Operators print tonnes of bauxite on a dry or wet basis, or do not say which. USGS bauxite mine production is in dry tonnes, so where the basis differs or is not stated the share is indicative.
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 bauxite mine. Shares of a country's output mix periods and bases, so treat them as indicative.
