Dowa Holdings (DOWAホールディングス株式会社,DOWA Hōrudingusu Kabushiki-gaisha) is a Japanesenonferrous metals manufacturer.[5] The company is a component of theNikkei 225stock index.[6]
Fujita-gumi, the forerunner of DOWA,[7] was established by three brothers fromYamaguchi prefecture in 1881. The brothers had personal connections with influential members of the government, so in 1884 they bought theKosaka mine, from which they expanded their business into various fields, centered on the coal mining business.[8] After the purchase, Fujita-gumi increased its capital and invested heavily in skilled labor and equipment. By 1888, theKosaka mine became Japan's top producer of silver.[8]
In 1900, an engineer at Kosaka succeeded in extracting copper by accessingkuroko (black ore — a mixture of copper, zinc and lead) deep in the mine. After that, Kosaka changed its focus from silver to copper, and in 1907, became Japan's largest copper producer.[7]
Dowa Mining was an early developer ofYuzawa, a hot spring town usinggeothermal energy, in the late 20th century.[9]
As of April 2007, Dowa Holdings was Japan's largest silver smelter.[10]
Dowa Holdings built a recycling plant in Kosaka which has been operating since 2008, extracting minerals and valuable metals from old electronics parts. One of its subsidiaries, Kosaka Smelting and Refining, has reclaimed rare materials including gold, indium, andantimony. In 2010, the company was working on methods to reclaimrare-earth elements, which are harder to mine, such asneodymium anddysprosium.[11]
As of 2010, Dowa was one of the top three zinc producers in Japan.[12] As of 2016, Dowa Holdings possessed the technology for recovering 22 metals, includinggermanium,ruthenium,gallium, andselenium.[13] In 2017, Dowa Holdings was involved in recycling efforts by sorting through electronics wastes in search for gold, platinum,palladium, and additional rare metals.[14] As of 2018, Dowa Holdings had more than 6,000 employees.[15]
In April 2023, Mitsubishi Materials Corp took full ownership of Onahama Smelting & Refining after purchasing its stake in Dowa Holdings andFurukawa Co..[16]
As of July 2023, Dowa Holdings was the top producer worldwide of high-purity gallium.[17] In 2024, Dowa filed a patent for gold plating.[18] In 2024, Dowa was granted a patent for copper plating.[19]
Dowa's main business is in the recycling and metal processing.[20] Dowa has six business segments; Environment and Recycling, Smelting & Refining, Electronic Materials, Metal Processing, Heat Treatment, and Other which is real estate leasing, construction, management, and technical support services.[21][22]
Dowa Holdings has several subsidiaries, including Dowa Eco-System, Dowa Metals and Mining, Dowa Electronics Materials,[23][24] Dowa Metal Tech,[25] and Dowa Thermotech.[26]
