一、美国国内稀土生产及应用概况2009年美国未进行稀土矿开采,但是以前在美国加洲芒廷帕斯生产的稀土精矿被处理成镧精矿和镨钕产品(75%钕、25%镨)。2009年美国继续销售库存的稀土精矿、中间化合物及单一稀土氧化物,并且继续保持稀土产品主要进口国、出口国和消费国地位。据估计,2009年美国稀土加工产品进口额大约为8400万美元,比2008年的1.86亿美元下降了许多。
First, the United States domestic production and application of rare earth rare earth ore mining in 2009 the United States did not, but previously in the United States Mountain Genesis produced rare earth concentrate processed into lanthanum concentrate and praseodymium neodymium products (75% neodymium, 25% praseodymium). In 2009, the United States continued to sell its stock of rare earth concentrates, intermediate compounds and single rare earth oxides, and continued to maintain its position as a major importer, exporter and consumer of rare earth products. It is estimated that in 2009 the U.S. imports of rare earth processed products will be about 84 million U.S. dollars, down from 186 million U.S. dollars in 2008.
