Besshi Copper Mine
The was a rich source of copper in Niihama, Ehime Prefecture, Japan. The deposits were discovered in 1690, and copper mining began in the following year. From then until the closing of the mine in 1973, Besshi produced about 700,000 tons of copper, and contributed to Japan's trade and modernization. The Sumitomo family managed the mine, which helped build the Sumitomo ''zaibatsu.'' The Dōzan River The is the largest branch of the Yoshino River and flows through Ehime and Tokushima is a prefecture of Japan located on the island of Shikoku. Tokushima Prefecture has a population of 728,633 (1 October 2019) and has a geographic area ... was named after the copper mine. The Minetopia Besshi theme park uses some of the mine's facilities.

Sumitomo Group
The is one of the largest Japanese ''keiretsu'', or business groups, founded by Masatomo Sumitomo (1585-1652) around 1615 during the early Edo period. History The Sumitomo Group traces its roots to a bookshop in Kyoto founded circa 1615 by Masatomo Sumitomo, a former Buddhist monk. Even today management of the group is guided by his "Founder's Precepts", written in the 17th century. Copper refining made the company famous. Riemon Soga, Masatomo Sumitomo's brother-in-law, learned Western methods of copper refining. In 1590 he established a smelting business, ''Izumiya'', literally meaning "spring shop". Riemon perfected techniques that allowed the extraction of silver from copper ore, something Japanese technology had not previously accomplished. The smelting and smithing business was moved from Kyoto to Osaka by the late 17th century. Soga passed control of the company to his son Tomomochi who managed its transformation into a major trading house during the Edo period. Sumitom ...

Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

Copper Mining
Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated (concentrated). The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite), the ore is crushed and ground to liberate the valuable minerals from the waste ('gangue') minerals. It is then concentrated using mineral flotation. The concentrate is typically sold to distant smelters, although some large mines have smelters located nearby. Such colocation of mines and smelters was more typical in the 19th and early 20th centuries, when smaller smelters could be economic. The sulfide concentrates are typically smelted in such furnaces as the Outokumpu or Inco f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Zaibatsu
is a Japanese language, Japanese term referring to industrial and financial vertical integration, vertically integrated business conglomerate (company), conglomerates in the Empire of Japan, whose influence and size allowed control over significant parts of the Japanese economy from the Meiji period until the end of World War II. A ''zaibatsu'' general structure included a family-owned holding company on top, and a bank which financed the other, mostly industrial subsidiaries within them. Although the ''zaibatsu'' played an important role in the Japanese economy from the 1860s to 1945, they increased in number and importance following the Russo-Japanese War of 1904–1905, World War I and Japan's subsequent attempt to conquer East Asia during the inter-war period and World War II. After World War II they were dissolved by the Occupation of Japan, Allied occupation forces and succeeded by the ''keiretsu'' (groups of banks, manufacturers, suppliers, and distributors).
