Indonesia Industrial Machinery Suppliers

PT Amman Mineral Internasional is one of Indonesia's largest copper and gold mining companies, operating the Batu Hijau mine on Sumbawa Island and developing the nearby Elang project. The company is majority-owned by Indonesian conglomerate Medco Energi, reflecting the government's push for greater domestic ownership of strategic mineral assets. Batu Hijau is a world-class copper-gold porphyry deposit that has been in production since 2000, producing copper concentrate and gold doré for export to smelters across Asia. Amman Mineral has invested heavily in downstream processing, including a new copper smelter and precious metals refinery in West Sumbawa, part of Indonesia's policy to onshore mineral processing. For B2B buyers, Amman Mineral supplies copper concentrate, gold and silver to smelters, refiners and metal traders in Japan, China, South Korea and beyond. Its growing smelting capacity, long mine life and strategic position in the Asia-Pacific copper supply chain make it an increasingly important supplier in the region.
