ياعزيزي انت تتحدث عن المعادن وكانها صادرات الحديد وفقط
الصين تسطيع شل الصناعات التكنولوجيه الامريكيه حرفيا اذا منعت تصدير تلك المعادن
China presently produces more than 95% of all rare earth materials that are vital in the creation of a big variety of electronic technologies including lithium car batteries, solar panels, wind turbines, flat-screen television, compact fluorescent light bulbs, petroleum-to-gasoline catalytic cracking, and military defense components such as missile guidance systems. It also dominates abilities to process them. This enables it to attract product manufactures to operate there as a condition of doing business, ration exports to maximize prices, and punish nations that don’t go along with its policy interests through supply embargoes. Beijing reduced rare earth shipments by 9% in 2010 over 2009, and has recently announced plans to reduce exports by another 35%.
China produces the vast majority of two particularly important rares, dysprosium (99 percent) and neodymium (95 percent). The motor of a Prius requires about 3 pounds of the latter. While other countries, including the U.S., have significant amounts of these, China’s low-cost labor and lax environmental restrictions has afforded it a big advantage in this mining-intensive industry.
Last year Congress required the Pentagon to examine the use of rare earth materials in defense applications to determine if non-U.S. supplies might be disrupted and identify ways to ensure adequate supplies by 2015. In response, the Pentagon sent back an unpublished report last month titled “Rare Earth Materials in Defense Applications” which concluded that the military is in pretty good general shape except for yttrium, an element used mostly in lasers. While China produced about 98% of the world’s yttrium in 2011, U.S. natural reserves of that material are about half as large.
