توضیحاتی درمورد کتاب به خارجی

Washington: CRS, 2012. 31 pages. Марк Хамфрис. Редкоземельные элементы: глобальная цепь поставок. Отчёт (Report) R41347 на англ. языке. Издатель – CRS (Congressional Research Service – Исследовательская служба Конгресса США), – это группа сотрудников Библиотеки Конгресса США (Library of Congress), занимающихся исследовательской деятельностью по запросам комитетов и отдельных членов этого законодательного органа. В отчёте рассмотрены мировые ресурсы и поставки РЗЭ в масштабах мировой экономики, что имеет геополитическое значение, т.к. их использование связано с вопросами национальной безопасности, «торговых войн» и т.п. Отчёт составлен для членов Конгресса США, но также будет полезен преподавателям, аспирантам и студентам, специализирующимся в области мировой экономики и международных отношений. Резюме на английском языке приведено в авторской редакции Марка Хамфриса.
Summary.
The concentration of production of rare earth elements (REEs) outside the United States raises the important issue of supply vulnerability. REEs are used for new energy technologies and national security applications. Is the United States vulnerable to supply disruptions of REEs? Are these elements essential to U.S. national security and economic well-being? There are 17 rare earth elements (REEs), 15 within the chemical group called lanthanides, plus yttrium and scandium. The lanthanides consist of the following: lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium. Rare earths are moderately abundant in the earth’s crust, some even more abundant than copper, lead, gold, and platinum. While more abundant than many other minerals, REEs are not concentrated enough to make them easily exploitable economically. The United States was once self-reliant in domestically produced REEs, but over the past 15 years has become 100% reliant on imports, primarily from China, because of lower-cost operations. There is currently some new rare earth mine production in the United States at Molycorp’s Mountain Pass mine. U.S.-based Molycorp also operates a separation plant at Mountain Pass, CA, and sells rare earth concentrates and refined products from previously mined above-ground stocks. Neodymium, praseodymium, and lanthanum oxides are produced for further processing but these materials are not turned into rare earth metal in the United States. Molycorp anticipates production at full capacity (19,050 metric tons) in the second half of 2012. Molycorp announced plans to purchase Neo Materials Technology, a rare earth processor and producer of permanent magnet powders with facilities in China and establish a joint venture with Daido Steel and Mitsubishi Corporation of Japan to produce neodymium-iron boron magnets in Japan. Some of the major end uses for rare earth elements include use in automotive catalytic converters, fluid cracking catalysts in petroleum refining, phosphors in color television and flat panel displays (cell phones, portable DVDs, and laptops), permanent magnets and rechargeable batteries for hybrid and electric vehicles, and generators for wind turbines, and numerous medical devices. There are important defense applications, such as jet fighter engines, missile guidance systems, antimissile defense, and space-based satellites and communication systems. World demand for rare earth elements is estimated at 136,000 tons per year, with global production around 133,600 tons in 2010. The difference is covered by previously mined above-ground stocks. World demand is projected to rise to at least 185,000 tons annually by 2015. Additional mine capacity at Mt. Weld Australia is expected to come onstream in 2012, to help close the raw materials gap in the short term. Other new mining projects could easily take 10 years to reach production. In the long run, however, the USGS expects that global reserves and undiscovered resources are large enough to meet demand. In March 2012, the Obama Administration announced the filing of a World Trade Organization case against China, citing unfair trade practices in rare earths. Several legislative proposals have been introduced in the 112-th Congress in the House and Senate to address the potential of U.S. supply vulnerability and to support domestic production and supply chain development of REEs because of their applications for national security/defense systems and clean energy technologies. The House Committee on Natural Resources approved H.R. 2011, the National Strategic and Critical Minerals Policy Act of 2011, on July 20, 2011. .
