摘　　要：针对铁物相分析过程中的磁铁矿与假象赤铁矿中铁含量进行了细致的分析研究。在氧化条件下,磁铁矿可一定程度转变为赤铁矿,并保留磁铁矿的形态,称假象赤铁矿。相关文献与资料中研究的铁物相分析过程中第一部是进行磁选,即用磁铁和磁选比色管将磁性铁磁选出来,此步骤磁选出的铁为具有磁性的铁,其中主要成分为磁铁矿与假象赤铁矿。本文对磁铁矿与假象赤铁矿中铁的含量进行了细致的分析研究,找到了合适的方法可以快速准确的测定铁矿石中磁铁矿与假象赤铁矿中铁的含量。The iron content in magnetite and martite in the iron phase analysis process was analyzed and investigated in detailed.Magnetite can turn into hematite under oxidation conditions to a certain extent,and the form of magnetite can be kept,it can be called martite.In the related literature and documents,the first step in the study of iron phase analysis is magnetic separation,the magnetic iron can be separated by magnet and magnetic color comparison tube,at this step,the iron separated by magnetic separation is iron with magnetism,the main composition is magnetite and martite.The iron content in magnetite and martite is analyzed and investigated detailed,and we found the proper method for fast and accurate determination of iron content in magnetite and martite of iron ore.
