Huayue Nickel Cobalt: a cobalt operation in Indonesia
Huayue Nickel Cobalt is a nickel-cobalt processing plant producing cobalt in Indonesia, operated by PT Huayue Nickel Cobalt. The sources report 8,023 tonnes cobalt in mixed hydroxide precipitate (MHP) for CY2025; the basis is the whole operation. In cobalt content, whole-operation output for CY2025 is 8,023 tonnes: about 2.6% of world cobalt output in 2025 and about 18% of Indonesia's; it is one of 4 operations on this site whose output can be stated in cobalt content.

How the cobalt-content figure is worked out. Nickel Industries reports 8,023 tonnes of cobalt in mixed hydroxide precipitate for the whole project. World mine production of cobalt in 2025 was 310,000 tonnes (USGS Mineral Commodity Summaries 2026); Indonesia produced 44,000 tonnes.
Status: operating in CY2025.
- The figure comes from Nickel Industries' annual report, as a 10% holder; the province is not stated in the sources used.

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