一、前言 据地质部门勘探查明,我国稀土工业储量为3700万吨,约占全世界总储量的80％。80年代以来,我国生产能力为12,000吨/年REO,已成为世界上主要稀土生产国。如所周知,我国稀土矿主要产地在内蒙白云鄂博,是包钢铁矿石的副产品——氟碳铈镧矿,其次是江西寻邬和龙南的独居石。我国已探明的稀土矿按目前年开采量计算,至少可延续三百年。因此,我们要凭藉这得天独厚的资源优势,努力提高精选、分离及萃取技
I. Foreword According to geological department exploration, it is found that China’s rare earth industrial reserves are 37 million tons, accounting for about 80% of the total reserves in the world. Since the 1980s, China’s production capacity of 12,000 tons / year REO, has become the world’s major producers of rare earths. As we all know, the main origin of China’s rare earth ore in Inner Mongolia Bayan Obo, is a by-product of iron and steel briquette - bastnaesite, followed by Jiangxi to find Wu and Longnan monazite. China has proven rare earth mines calculated according to the current year, at least for three hundred years. Therefore, we must strive to improve the selection, separation and extraction technology by virtue of this unique resource advantage
