SMM Field Trip to Indonesia’s aluminum industry: Fourth stop – Antam Tbk – UBP Bauksit Tayan

On June 9, 2025, Ju Anran, Senior Manager of SMM’s Aluminum Division, and Liu Xinyi, Analyst of SMM’s Aluminum Division, led a delegation on a field trip to visit Indonesia Chemical Alumina (ICA), a bauxite mine and chemical-grade alumina refinery owned by PT Aneka Tambang Tbk (Antam) in Indonesia.

PT Aneka Tambang Tbk, established in 1968 and headquartered in Jakarta, is wholly owned by the state-owned holding company PT Mineral Industri Indonesia (Persero). The company’s main businesses include the mining and sales of mineral resources such as nickel, gold, and bauxite. In 2024, Antam achieved a bauxite production of 1.1 million wmt and a chemical-grade alumina production of 180,000 mt, providing a solid resource guarantee for Indonesia’s domestic industry chain.

To promote deep processing of ores, Antam, in collaboration with Inalum, invested US$941 million to build a smelting-grade alumina refinery with an annual capacity of 1 million mt in Mempawah, West Kalimantan. The project officially commenced operations in September 2024. Antam is responsible for supplying high-quality ore raw materials, achieving a seamless connection from the mine to the alumina refinery.
