In recent 10 years, global NdFeB magnetic materials industry develops at the increasing speed over 20% every year, which strongly stimulates the fast production improvement of neodymia and neodymium metal. Thereinto, ...In recent 10 years, global NdFeB magnetic materials industry develops at the increasing speed over 20% every year, which strongly stimulates the fast production improvement of neodymia and neodymium metal. Thereinto, production of Chinese NdFeB enhances the most rapidly. In 2004, output of Chinese sintered NdFeB reached 25,000 tons, up 82.5% over previous year. 1. 2004 Chinese Neodymia Production (1) Production of Southern Ore According to statistics, total 30,000 tons of展开更多
