The Jiaman project is located in Maluku Province, Indonesia. The construction scale is to produce 40,000 tons of high nickel matte per year. It uses oxygen-enriched side-blowing smelting to process laterite nickel ore, and produces low nickel matte through reduction and sulfidation. Low nickel matte is treated by multi-gun top blowing furnace, and high nickel matte products containing 70% nickel are produced. This project is the world's first multi-gun top-blowing furnace to blow low nickel matte into high nickel matte, and will be put into production in April 2025.
