Weda Bay Nickel: a nickel operation in Indonesia
Weda Bay Nickel is a nickel pig iron operation producing nickel in Indonesia, operated by PT Weda Bay Nickel. The sources report 35.8 kt-Ni content, nickel pig iron (NPI), PT WBN NPI plant for CY2025; the basis is 100% of the nickel pig iron plant (not the mine). The sources do not give a whole-operation figure in nickel content that can be compared with world output, so no share is computed.
Who owns and operates it?

How much does it produce?
| Period | Output | Basis | Where in the source |
|---|---|---|---|
| CY2025 | 35.8 kt-Ni content, nickel pig iron (NPI), PT WBN NPI plant | 100% of the nickel pig iron plant (not the mine) | PDF p.20, Appendix 3 table row "NPI production - PT WBN (100% basis - kt-Ni content)", FY 2025 column; text PDF p.11 · Eramet |
| CY2024 | 30.5 kt-Ni content, nickel pig iron (NPI) | 100% of the nickel pig iron plant (not the mine) | PDF p.20, same row, FY 2024 column · Eramet |
Status: operating, as of 31 December 2025.
- The figure comes from Eramet, a minority holder with 38.7% indirect, which labels it as a 100% basis. It covers the nickel pig iron plant only: the mine also sold about 38.5 million wet tonnes of ore externally in 2025 (Eramet), so nickel mined at Weda Bay is far larger than the figure shown, and no share of world output is computed.
- Eramet's NPI sales line (15.8 kt of nickel) is its 43% share under an off-take contract and is not whole-operation output.

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 nickel content 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.
- 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 nickel mine. Shares of a country's output mix periods and bases, so treat them as indicative.
