Huayue Nickel Cobalt (nickel): a nickel operation in Indonesia
Huayue Nickel Cobalt (nickel) is a high-pressure acid leach plant producing nickel in Indonesia, operated by PT Huayue Nickel Cobalt. The sources report 85,031 tonnes of nickel in mixed hydroxide precipitate (MHP) for CY2025; the basis is the whole operation. In nickel content, whole-operation output for CY2025 is 85,031 tonnes: about 2.2% of world nickel output in 2025 and about 3.3% of Indonesia's; it is one of 8 operations on this site whose output can be stated in nickel content.

How the nickel-content figure is worked out. Nickel Industries reports that the Huayue Nickel Cobalt project produced 85,031 tonnes of nickel in mixed hydroxide precipitate; the 10% attributable table (8,503 t) is consistent with this. World mine production of nickel in 2025 was 3,900,000 tonnes (USGS Mineral Commodity Summaries 2026); Indonesia produced 2,600,000 tonnes.
Status: operating, as of 31 December 2025.
- The figure comes from Nickel Industries' annual report, as a 10% holder; the operator is PT Huayue Nickel Cobalt, which is not the reporting party. The cobalt output of the same plant is listed under cobalt.
- 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.
