Mitsubishi Materials Corporation, together with its subsidiaries, engages in the production and sale of precious metals, cement products, advanced materials and tools, electronic materials and components, copper, aluminum, and other products. 
The company is also a producer of gold; it refines and manufactures gold bars at its Naoshima Smelter. It's annual gold refining capacity is about 60 tons as of 2009.
Mitsubishi Materials Corporation was established in 1990 through the merger of Mitsubishi Metal Corporation and Mitsubishi Mining & Cement Co Ltd.
The former Mitsubishi Metal Corporation, established in 1950, had absorbed the pre-war non-ferrous mining, smelting and refining interests of Mitsubishi.
Although the main source of its newly-mined gold output is the byproduct of large copper smelting operations, the company had been involved in the mining of gold from 1870 until the Sado gold mine at Niigata was closed in 1989.
Between 1893 and 1989, all gold refining took place at the company’s Osaka Refinery. In 1989, gold refining operations were transferred to the Naoshima Smelter, originally established in 1917.
