摘要 为给齐大山含碳酸盐铁矿石选矿利用提供理论支持,对矿石的化学组成、矿物组成、矿石的结构构造、矿物产出形式、嵌布特征及嵌布粒度等进行了详细研究。结果表明:矿石中的铁主要赋存于菱铁矿、赤铁矿和磁铁矿中,主要的脉石矿物为石英和白云石;磁铁矿与赤铁矿共生关系密切,大部分赤铁矿由磁铁矿氧化蚀变生成,且嵌布粒度较细;菱铁矿与白云石、石英紧密连生,主要以自形-半自形的粒状集合体产出,粒度粗大;菱铁矿和赤铁矿-磁铁矿在大于0.1 mm粒级的分布率分别为92.90%、15.00%。当矿石粒级为-0.053 mm时,铁矿物单体解离度达到60%以上。矿石的工艺矿物学特征表明,矿石属于难选铁矿石。 In order to provide theoretical support for the efficient utilization of Qidashan carbonated iron ore,the chemical components,the mineral composition,production form and dissemination characteristics of iron ore were studied in detail.The results show that the iron in the ore mainly occurs in siderite,hematite and magnetite.Main gangue minerals are quartz and dolomite.Magnetite and hematite have a close associated relationship with each other.Most hematite is formed by magnetite oxidation alteration,and hematite has a fine-grained dissemination.Siderite is closely associated with dolomite and quartz,it is mainly composition coarse particles aggregate with self form and semi-self form.Siderite and hematite-magnetite were 92.90%and 15.00%respectively in the grain size above 0.1 mm.The liberation degree of iron ore is more than 60%in particle size below 0.053 mm.The process mineralogy analysis of the ore shows that the ore belongs to refractory iron ore.
