According to the research, each ton of coal mine will pollute 1 cubic meter to 2.5 cubic meters of water resources. [10] Mine water is essential for mine operation. In the process of mining, mine water will be contaminated with different intensity, especially acidic chemicals which formed acid mine drainage (AMD). A large number of sulfides ...

China has many different types of mineral resources and has global significant reserves of many of them. [2] They are frequently in the global top 10 countries for mineral reserves or production. [46] [2] They produce more than 90% of the global rare earth element ore. [47]
It contains plentiful natural resources, including mineral ores, oil and gas. These rich mineral resources explain why the Central Asian Orogenic Belt is also called the Central Asian metallogenic domain, which is one of the largest metallogenic domains in the world.

Mining in Japan is minimal because Japan does not possess many on-shore mineral resources. [1] Many of the on-shore minerals have already been mined to the point that it has become less expensive to import minerals. There are small deposits of coal, oil, iron and minerals in the Japanese archipelago. [2]
The following list of mines in the Philippines is subsidiary to the Lists of mines in Asia article and Lists of mines articles. This list contains working, defunct and future mines in the country and is organised by the primary mineral output(s) and province. For practical purposes stone, marble and other quarries may be included in this list.
In 2006, Cambodia's mineral resources remained, to a large extent, unexplored. Between 2003 and 2006, however, foreign investors from Australia, China, South Korea, Thailand, and the United States began to express their interest in Cambodia's potential for offshore oil and gas as well as such land-based metallic minerals as bauxite, copper, gold, and iron ore, and such industrial minerals as ...
Polymetallic nodules are found in both shallow (e.g. the Baltic Sea [7]) and deeper waters (e.g. the central Pacific), even in lakes, [8] and are thought to have been a feature of the seas and oceans at least since the deep oceans were oxygenated in the Ediacaran period over 540 million years ago.
