Amman's 900,000-tonne smelter project ready to support downstreaming

PT Amman Mineral Internasional Tbk (AMMAN) has reported that its National Strategic Project (PSN) copper smelter, designed to process up to 900,000 metric tonnes of concentrate per year, has been completed and is ready to support the national downstreaming programme. “The completion of this smelter project is an important achievement for Amman. Behind it lies hard work, resilience, and strong collaboration from all employees and our partners in facing various challenges during the construction and commissioning process,” said Amman President Director Arief Sidarto in an official statement confirmed on Saturday. The project’s completion was formalised through the signing of a Completion and Project Acceptance Certificate (PAC) between Amman and its strategic partner, China Nonferrous Metal Industry’s Foreign Engineering and Construction Co., Ltd. (NFC), at NFC’s headquarters in Beijing, China. The PAC signing marks the conclusion of all construction work and the resolution of commissioning-related punch list items that were part of the contract’s scope. Although the Amman copper smelter has been operating for more than a year, this important milestone confirms that the smelter has successfully met all performance guarantee tests as required by the contract and has officially entered the long-term operational phase. Looking ahead, Amman hopes the policy ecosystem supporting the competitiveness of the domestic processing and mining industry can continue to be strengthened so that Indonesia is able to maximise the benefits of downstreaming and remain competitive amid global dynamics. As a National Strategic Project, the Amman copper smelter is designed to process up to 900,000 metric tonnes of concentrate per year sourced from the Batu Hijau mine and, in the future, the Elang mine. This integrated complex will produce high-quality copper cathodes, gold, silver, sulphuric acid, and selenium, which are important materials for various sectors underpinning economic growth and the global energy transition.
