The South Korean government announced on the 20th that it has acquired the exclusive exploration rights of the manganese corner in the Magellan submarine mountain area in the high seas of the western Pacific Ocean in the eastern part of the Philippines. The size of the mining area obtained this time is 3,000 square kilometers, which is equivalent to 1034 times the area of ​​Seoul's Yeouido (about 2.9 square kilometers). Manganese angle is a mineral resource formed in seamounts by adsorbing metal contained in seawater. It is rich in elements such as cobalt, nickel, copper, and manganese, and can be used as industrial raw materials for electric and electronics, steelmaking, and precious metals.
The South Korean Ministry of Foreign Affairs and the Ministry of Maritime Affairs and Fisheries said on the same day that “At the 22nd General Assembly of the International Seabed Association (ISA), the exploration license for the mining area was finally obtained.†“Through this decision, following the Pacific manganese nodule mining area, the Indian Ocean submarine hydrothermal deposit After the mining area and other areas, South Korea has acquired the exclusive exploration rights for the fifth mining area.†The manganese horn buried in the exploration area contains high levels of cobalt and rare earths, and is cheaper to extract than manganese mines located deeper in water depth. This is a very concerned degree. In the vicinity there are mining areas in China, Japan, Russia and Brazil.
The government expects that 40 million tons of manganese horns will be buried in the mining area. If 1 million tons is put into commercial production every year, the import substitution effect of 6 trillion won will be generated in the next 20 years. The government plans to sign an exploration contract with ISA in 2018, and after the final exploration of the selected mining area through precision exploration, it will be formally put into commercial production by the private sector.
The government explained that South Korea has thus become a country with exclusive exploration rights to three types of minerals (manganese nodules, submarine hydrothermal deposits, and manganese corners) on the high seas. The only countries that previously had exclusive exploration rights for all three minerals were China and Russia. Manganese nodules are similar in composition to manganese angles (depths of 800 to 2500 meters), but they differ in the distribution area (deep water 4500 to 5000 meters) and appearance. Submarine hydrothermal deposits are mineral resources formed by the precipitation of metal ions during the gushes of heated hot water.
Plastic
Drag Chain (Plastic Cable Drag Chain) can be used
as a component or service parts in glass machinery, handing and transport
machinery, painting and decoration equipment, shoe-making machinery, chemical
machinery, textile machinery, welding machines, automatic welding system,
plastic machinery etc.
After a series of tests, we arrived
at the same conclusion that our plastic drag chain (plastic cable
drag chain) can withstand about 15 million movements. The quality of our plastic drag chain (plastic Cable Drag Chain) is guaranteed.
