稀土是我国富有资源。随着冶金工业的发展,每年将提供大量低品位稀土精矿,其主要成份为:RxOy20-25%,Fe15-20%,CaO20-25%,F10-15%,SiO_2 2-4%。以这种稀土精矿为原料,通过火法冶金或湿法冶金,可制得稀土中间合金、稀土金属及各种稀土化合物等产品,其中数量最大的是稀土中间合金。稀土精矿中的铁对冶炼稀土中间合金流程 Rare earth is rich in resources in our country. With the development of the metallurgical industry, a large number of low grade rare earth concentrates will be provided each year. The major components are: RxOy 20-25%, Fe 15-20%, CaO 20-25%, F 10-15% and SiO 2 2-4%. The rare earth concentrate as raw material, through pyrometallurgy or hydrometallurgical, can be made of rare earth master alloys, rare earth metals and various rare earth compounds and other products, of which the largest number of rare earth master alloys.
