Ramu nickel-cobalt (nickel): a nickel operation in Papua New Guinea
Ramu nickel-cobalt (nickel) is a high-pressure acid leach plant producing nickel in Papua New Guinea, operated by MCC (Metallurgical Corporation of China). The sources report 33,007 tonnes contained nickel in MHP for CY2025; the basis is the whole operation. In nickel content, whole-operation output for CY2025 is 33,007 tonnes: about 0.8% of world nickel output in 2025; it is one of 8 operations on this site whose output can be stated in nickel content.
Who owns and operates it?
| Owner | Interest | As of |

| Nickel 28 Capital | 8.56% | 23 February 2026 |
How much does it produce?
| Period | Output | Basis | Where in the source |
|---|---|---|---|
| CY2025 | 33,007 tonnes contained nickel in MHP | Whole operation | p.1 highlights; operating table "Contained Nickel (tonne)", Full Yr 2025 · Nickel 28 Capital Corp. |
| CY2024 | 28,669 tonnes contained nickel in MHP | Whole operation | p.1 highlights; operating table Full Yr 2024 · Nickel 28 Capital Corp. |
Between CY2024 and CY2025 the reported figure rose by 15.1%, in the same unit and on the same basis.
How the nickel-content figure is worked out. Nickel 28 reports 33,007 tonnes of contained nickel in mixed hydroxide precipitate for the whole Ramu operation. World mine production of nickel in 2025 was 3,900,000 tonnes (USGS Mineral Commodity Summaries 2026).
Status: operating, as of 23 February 2026.
- The figure comes from Nickel 28's release, as an 8.56% holder; the operator is MCC, which is not the reporting party. The release calls its figures unaudited and preliminary.
- The figure is nickel in the processed product (nickel pig iron, ferronickel, mixed hydroxide or sulfide), not nickel mined, and it is compared with USGS mine production, so the share of world output is indicative.

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.
