摘要： 通过MLA自动检测技术、XRD等手段,对吉林省羚羊铁矿石进行了详细的工艺矿物学研究.查明了该铁矿石的化学组成、矿物组成、粒度组成及嵌布特征.结果表明:铁矿石中的铁主要赋存于磁铁矿和菱铁矿之中,少量的铁存在于鲕绿泥石和磁绿泥石等铝硅酸盐矿物之中.羚羊铁矿石矿物组成非常复杂、嵌布粒度很细、铁矿物与脉石紧密共生,且脉石矿物易泥化,属于难选铁矿石.该研究结果可作为此铁矿资源合理开发利用的参考依据.

Abstract: Through the MLA automatic detection, XRD and other measurements, the detailed mineralogical process studies on the Lingyang iron ore in Jilin Province were carried out to identify the chemical composition, mineral composition, grain composition and dissemination characteristics of the ore. The results showed that iron mainly occurs in form of magnetite and siderite, and small amounts of iron exists in chamosite and berthierine. Lingyang iron ores are refractory due to complex composition, fine disseminated and iron minerals locking closely with gangue mineral. The results may provide the basic references for the rational exploitation of the iron ore resources.
