摘　　要：采用显微镜、X射线衍射、重砂分离、化学分析等手段,详细研究了攀枝花铁矿中钪的分布规律.结果表明,矿石中钪在钛普通辉石中的分配率最高,其次为钛铁矿和钛磁铁矿,斜长石和硫化物中钪的含量及分配率极低。选矿产品中钪的分布与走向与钛普通辉石及钛铁矿相近.电选尾矿、重选尾矿、铁精矿、钛精矿是钪的主要富集产物,也是综合回收钪的主要原料。对各产品中钪的综合回收途径进行了探讨.The distribution law of scandium in the Panzhihua iron ore has been studied in detail by means of the optical microscope,X-ray diffraction,mineral separation techniques and chemical analysis etc.It is shown that the order of the scandium distribution in the ore is that the titanaugitc takes the first place,the titanioferrite and the titanomagnetite take the second place,and the feldspar and the sulphides take the third place,and the distribution of scandium in the mineral processing products is similar to that in the titanaugite and the titanioferrite.The tailings from electrostatic separation and gravity concentration,titanium concentrate and iron concentrate are main scandium-enriched products and the major row materials for the comprehensively recovering scandium.Also, the possible techniques recovering scandium from various products are discussed in the paper.
