| 摘 要： | 通过偏光显微镜、扫描电镜，对含稀土高炉渣的矿物组成和钍的赋存状态进行了分析研究。结果表明：黄长石、枪晶石、二价金属硫化物、铈钙硅石是构成高炉渣的主要矿物。元素钍存在于稀土矿物中，其自身不能形成独立矿物，而是以类质同像混入物的状态分散于铈钙硅石矿物中。

| Abstract: | The mineral composition of blast furnace slags containing rare earths and the occurrence state of thorium were analyzed and researched using the polarization microscope and scanning electron microscope. The practice showed that the blast furnace slags mainly consisted of melilite,cuspidine,bivalent metallic sulphide and Ce-Ca silica. The element thorium existed in the rare earths mineral and can not form an independent mineral ,but scatter as mixed isomorphism matter in the Ce-Ca silica. |
