资料显示,目前,我国稀土选冶、分离的工艺水平处于世界领先地位。我国北方包头轻稀土矿为铁、稀土多金属共生矿;我国南方江西、广东等地独有的离子型稀土矿的结构、成分复杂。这一北一南两种稀土资源的选冶均无可借鉴的工艺。经过“六五”、“七五”的科技攻关,我国解决了两种资源选冶难题,为产业化铺平了道路。“七五”以后,北方轻稀
Data show that at present, China’s rare earth metallurgy, separation of the level of technology in the world’s leading position. Baotou light rare earth ore in northern China is iron and rare earth polymetallic symbiotic ore; the structure and composition of the ionic rare earth mine unique to Jiangxi, Guangdong and other places in southern China are complex. The north one south of rare earth resources, metallurgy and metallurgy are no reference technology. After the “65” and “75” scientific and technological tackles, our country has solved the two problems of resource selection and metallurgy and paved the way for industrialization. “Seven five ” after the north light and thin
