PT Merdeka Battery Materials Tbk is an Indonesia-based vertically integrated mining and mineral processing company focused on the extraction, refining, and supply of critical materials for the global electric vehicle battery and stainless steel manufacturing industries. Founded in 2019 and headquartered in South Jakarta, Indonesia, the company operates as a key subsidiary of PT Merdeka Copper Gold Tbk, maintaining large-scale upstream mining concessions in Southeast Sulawesi and integrated downstream processing assets within the Indonesia Morowali Industrial Park in Central Sulawesi. The company operates across multiple specialized segments encompassing nickel ore mining, pyrometallurgical smelting, hydrometallurgical processing, and industrial chemical manufacturing. Its primary products and services include saprolite and limonite nickel ores mined from the Sulawesi Cahaya Mineral concession; nickel pig iron produced via rotary kiln electric furnace smelters operated through PT Bukit Smelter Indonesia, PT Cahaya Smelter Indonesia, and PT Zhao Hui Nickel; low-grade and high-grade nickel matte for conversion into battery-grade chemicals; mixed hydroxide precipitate produced via high pressure acid leach processing; and industrial chemicals and by-products, including sulfuric acid, iron ore pellets, copper sponge, and industrial steam manufactured through the Acid Iron Metal project. In recent major strategic developments, the company completed a landmark initial public offering on the Indonesia Stock Exchange to finance its downstream value-chain integration. Operational expansions and corporate initiatives include the acquisition of a controlling equity stake in PT Huaneng New Metal Industry to convert low-grade matte into high-grade nickel matte, the commercial commissioning of the Zhao Hui Nickel smelter facility, the formation of a joint venture with GEM Co., Ltd. to construct the PT ESG New Energy Material high pressure acid leach plant for mixed hydroxide precipitate production, and the commissioning of dedicated heavy-haul road infrastructure connecting the Sulawesi Cahaya Mineral mine directly to coastal industrial processing hubs.
