How To Promote Waxing At A Business
Europe, samarium, lanthanum, are merely the names of some of the 17 minerals that are part of the rare earths (in English "rare earth elements" or "rare earth metals) and are represented as the chemical elements in the periodic table.
materials from unusual names are a bit spread 'everywhere in the earth, whose extraction involves techniques not very different from traditional ones, but high levels of pollution by waste, even radioactive.
Without these 17 rare items you can not produce anything like what today gives birth industry's most advanced. Neodymium, for example, is vital to the production of batteries and electric or hybrid car engines, for computer hardware for mobile phones and cameras. Neodymium oxide in the military is an "ingredient" in the magnets necessary for operating the missile wings directional precision. With Europe being produced instead el'ittrio optical fibers and light bulbs 'green' Scandium is the raw material from stage lighting, while promising to serve the medical equipment of last generation.
early 90s Deng Xiaoping proclaimed that "China Rare Earth is one that is oil and the Middle East.", and currently none of the big corporations, from Philips to Siemens, with Nokia, Toyota, Hewlett Packard to Apple to Sony and Canon, can produce their most valuable assets without supplies from China.
ULE estimates say that 12% of the deposits in the United States, 18% in the former Soviet Union, smaller quantities are scattered in many other countries and, according to estimates, between 37% and 58% reside in China. We also find a lot of mines in Afghanistan, but the costs of extraction of rare earths is very expensive and not competitive with that of China that sells all over the world at a very low price. But since 2009 China has dramatically reduced the exports of rare earths, saying that it must preserve it for environmental reasons and for its own needs.
For 2011, China has already announced a further reduction in exports. The news worries the high tech industries, particularly in Japan to which Beijing has even blocked the export in September, during a dispute over sovereignty over a group of islands. Now Tokyo is planning to create a recycling of rare earths, as well as to seek substitutes. United States, Australia and other producers had stopped mining because they do not profitable in the face to cheap Chinese production. But now it has resumed the search and extraction of these minerals, though it will take time to achieve adequate production.
And Beijing shows every intention of using its market power in this field to force the rest of the world to accept its conditions: these include not only a net transfer of capital, but also work and especially trade secrets to the West from the People's Republic.
China in recent months, has made tremendous efforts in building a strategic reserve of rare earths. There are no known details of the storage site but as reported by Chinese state agencies, and the declarations of state enterprises and state media reports it appears that the complex was built in the region of Inner Mongolia. With a storage capacity of rare earth elements of the total amounting to more than exported last year from China (39,813 tons), the reserve could have the ability to affect the entire global market already largely dominated by China, which, in Today, controlling more than 90% of global production of rare earths.
