摘　　要：这是一篇矿业工程领域的论文。黑山铁矿主要矿物为钒钛磁铁矿、钛磁铁矿,因受制于矿石性质的影响,该类型矿床铁精矿品位普遍偏低,且富含钛、硅、镁等元素,限制了该类矿床资源的开发效益,若能在选矿过程中进一步提高铁精矿品位,将有助于提高矿山效益、降低铁精矿的冶炼成本。本文采用光学显微镜、矿物解离分析仪(MLA)、化学分析等方法,对该类型铁矿石进行了系统地研究。通过对样品中矿物组成、成分分析以及杂质矿物的种类、粒度、解离特征等方面的研究,查明了影响该类型铁精矿品质的矿物学因素。This is an essay in the field of mining engineering.The main minerals of Heishan iron mine are vanadium titanomagnetite and titanomagnetite.Due to the influence of ore properties,the grade of iron concentrate in this type of deposit is generally low and rich in titanium,silicon,magnesium and other elements,which limits the development benefits of this kind of deposit resources.If the grade of iron concentrate can be further improved in the beneficiation process,it will help to improve the mine benefits and reduce the smelting cost of iron concentrate.This paper systematically studies this type of iron ore by means of optical microscope,mineral dissociation analyzer(MLA)and chemical analysis.This type of iron ore was systematically studied by means of optical microscope,mineral dissociation analyzer(MLA)and chemical analysis.
