Ashio, Tochigi
was a town located in Kamitsuga District, Tochigi, Japan. As of 2003, the town had an estimated population of 3,465 and a density of 18.65 persons per km². The total area was 185.79 km². On March 20, 2006, Ashio, along with the city of Imaichi, the town of Fujihara, and the village of Kuriyama (both from Shioya District), was merged into the expanded city of Nikkō. The Ashio Copper Mine was located in Ashio. This copper mine caused a major pollution problem in Japan at the beginning of the 20th century. Subsequent environmental problems related to the mine are still evident along the river, in Tochigi, Gunma and Ibaraki Prefectures. In 1907 the Ashio miners rioted. During World War II a POW camp was based here to supply slave labour to the copper mines. The following communities agreed to seek the permission of the governor of the prefecture to merge on March 1, 2006: * Nikkō * Imaichi * Ashio * Fujihara * Kuriyama References * Nimura Kazuo.

List Of Towns In Japan
A town (町; ''chō'' or ''machi'') is a local administrative unit in Japan. It is a local public body along with prefecture (''ken'' or other equivalents), city (''shi''), and village (''mura''). Geographically, a town is contained within a district. Note that the same word (町; ''machi'' or ''chō'') is also used in names of smaller regions, usually a part of a ward in a city. This is a legacy of when smaller towns were formed on the outskirts of a city, only to eventually merge into it. Towns See also * Municipalities of Japan * Japanese addressing system The Japanese addressing system is used to identify a specific location in Japan. When written in Japanese characters, addresses start with the largest geographical entity and proceed to the most specific one. When written in Latin characters, ad ...

Ashio Copper Mine
The was a copper mine located in the town of Ashio, Tochigi (now part of the city of Nikkō, Tochigi), in the northern Kantō region of Japan. It was the site of Japan's first major pollution disaster in the 1880s and the scene of the 1907 miners' riots. The pollution disaster led to the birth of the Japanese environmental movement and the 1897 Third Mine Pollution Prevention Order. It also triggered changes in the mine's operations, which had played a role in the 1907 riots, part of a string of mining disputes in 1907. During World War II the mine was worked by POW forced labour. History Copper deposits are recorded as having been discovered in the area around the year 1550, but exploitation did not begin until two local households received an official permit in 1610 to establish a mine. In 1611, copper from the site was presented to officials of the shogunate; and shortly thereafter, Ashio was officially listed as a copper mine belonging to the Tokugawa shogunate. Copper, in ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pollution
Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of any substance (solid, liquid, or gas) or energy (such as radioactivity, heat, sound, or light). Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Although environmental pollution can be caused by natural events, the word pollution generally implies that the contaminants have an anthropogenic source – that is, a source created by human activities. Pollution is often classed as point source or nonpoint source pollution. In 2015, pollution killed nine million people worldwide (one in six deaths). This remained unchanged in 2019, with little real progress against pollution being identifiable. Air pollution accounted for of these earlier deaths. Major forms of pollution include air pollution, light pollution, litter, noise pollution, plastic pollution, soil contamination, radioactiv ...

Copper Mine
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] |
