摘　　要：根据工艺矿物学理论,在矿物组成、嵌布特征及工艺粒度等方面对研山铁矿石进行了研究,将该区域矿石可分为易解离易选型、易解离难选型、难解离难选型三种矿石类型。建议在选别作业时,将三种类型矿石合理配矿,进行阶段磨矿和阶段选别,达到提高选矿指标的目的。The mineral composition,dissemination characteristics, particle size and other aspects of Yanshan iron ore are studied in this paper based on process mineralogy. The ores in this area are divided into three types：first type that is easy to liberate and easy to beneficiate, second type that is easy to liberate and hard to beneficiate and third type is hard to liberate and hard to beneficiate. During the benefication, the three types of ore should be matched in proportion, and the iron ore should be used the stage-grinding and stage-concentration process in order to reach the goal of improving beneficiation results.
