| 摘 要： | 辽阳三道岭铁矿是近年来勘探开发的鞍山式贫铁矿床.对其工艺矿物学特征研究表明，三道岭铁矿石类型以原生的磁铁贫矿为主，化学成分简单，高硅，贫铁、镁、铝，低有害杂质硫和磷，具有鞍山式铁矿沉积变质贫铁石英岩的特征.矿石主要工业矿物为磁铁矿，其嵌布类型以连晶及嵌晶为主.粒度分析表明有用矿物中粗粒占82.45%，利于选矿.

| Abstract: | Sandaoling iron deposit in Liaoyang,Liaoning Province is a lately explored lean iron deposit of Anshan type.Study on its technological mineralogy indicates that the ore is mainly protogenic lean magnetite iron ore type.Its chemical composition is simple,with high silicon,low Fe,Mg and Al and lower deleterious impurities of S and P,belonging to typical sedimentary metamorphic magnetic quartzite of Anshan type.The major useful mineral is magnetite,whose dissemination feature is mainly of poecilitic and intergrowth.Granularity analysis shows that the useful mineral is mainly of coarse grain,which is suitable for mineral processing. |
