Nickel Industries' four RKEF plants: a nickel operation in Indonesia

Nickel Industries' four RKEF plants is a laterite ore smelting plant producing nickel in the Morowali and Weda Bay industrial parks, Indonesia. The sources report 124,966 tonnes of nickel in NPI (total nickel production) for CY2025; the basis is as reported by owner for the four RKEF plants combined. In nickel content, whole-operation output for CY2025 is 124,966 tonnes: about 3.2% of world nickel output in 2025 and about 4.8% of Indonesia's; it is one of 8 operations on this site whose output can be stated in nickel content.

Who owns and operates it?

Interests are as stated in the sources below on the date shown. Ownership changes with deals, so a stake may have changed since the date shown.

How much does it produce?

Between CY2024 and CY2025 the reported figure fell by 1.8%, in the same unit and on the same basis.

How the nickel-content figure is worked out. Nickel Industries reports 124,966 tonnes of nickel in NPI produced by its four RKEF plants (80%-owned subsidiaries it consolidates). The table is not labelled as a share, whereas the same report labels the Huayue HPAL figures "attributable (10%)", so it is read as the whole-plant total. 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 report gives one combined figure for the four RKEF plants (Hengjaya Nickel, Oracle Nickel and Ranger Nickel in the Indonesia Morowali Industrial Park, and Angel Nickel in the Indonesia Weda Bay Industrial Park); no per-plant split is printed.
• The Excelsior (ENC) HPAL project, in which Nickel Industries held 44% at year end, is listed as under construction in the same report and has no output line here.
• 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.
