Business
Sumitomo Metal Mining Co., Ltd. Sumitomo Metal Mining Co., Ltd. engages primarily in mineral resource development and operations; non-ferrous metal smelting and refining; and advanced materials production. The company produces copper, gold, nickel, and zinc concentrates through mining activities at nine mines across regions including Japan, Southeast Asia, North America, and South America; refines these into high-purity metals at eight smelters and refineries; and manufactures specialized materials such as battery cathode active materials for electric vehicles, crystal materials including lithium tantalate and lithium niobate for communication devices, powder materials like cesium tungsten oxide near-infrared absorbers and fine metallic powders, package materials encompassing copper-clad polyimide films (S’PERFLEX) and printed wiring boards, silicon carbide (SiC) substrates (SiCkrest) for power semiconductors, and catalysts for automobile exhaust purification and oil refining. Founded with roots tracing to 1590 through Sumitomo's copper business and formally established in 1905, Sumitomo Metal Mining maintains headquarters in Tokyo, Japan, and operates bases in 14 countries and regions with approximately 7,400 consolidated employees. Recent developments include a strategic equity investment and collaboration agreement with Nano One Materials Corp. finalized in late 2024, valued at C$16.9 million, to accelerate commercial production of lithium iron phosphate and nickel-rich cathode active materials using Nano One’s One-Pot process, alongside joint efforts in battery ecosystem development and supply chain risk mitigation. In May 2025, the company signed definitive agreements with Rio Tinto to acquire a 30% stake in the Winu copper-gold project in Australia, with Rio Tinto retaining 70% and operatorship, while expanding collaboration opportunities in copper, base metals, and lithium; transaction closure remains pending regulatory approvals. Additional advancements encompass a partnership with Toyota Tsusho for mass production of cathode materials tailored to all-solid-state batteries and the development of 100nm nano copper powder exhibiting enhanced oxidation resistance.
