通过光学显微镜、X射线衍射、化学分析等手段，对海城菱镁矿的工艺矿物学特性进行了研究。结果表明，矿石中有用矿物为菱镁矿，主要杂质矿物包括滑石、白云石、石英、斜绿泥石等，以及少量的黄铁矿及褐铁矿等。矿石嵌布粒度不均匀，菱镁矿以粗粒嵌布为主，与其他杂质矿物存在一定程度的充填穿插，且易单体解离。

The characterization of process mineralogy of the Haicheng magnesite ore has been investigated through optical microscope ,XRD and chemical analysis .The results show that besides the valuable mineral magnesite the primary gangue minerals were talc ,dolomite ,quartz ,clinochlore ,apatite ,little pyrite and limonite in the ore .The dissemination size of the ore is maldistribution .The dissemination size of magnesite minerals were thick and interspersed with other gangue minerals ,and easily to be dissociated .
