在苏联南阿尔丹铁矿区矿床中,广泛地发育着含蛇纹石矿物类型的磁铁矿矿石。这种类型的磁铁矿石在一些矿床的储量中几乎占50%,而在矿体的表层所占比例还要大一些。这种矿石的工艺性质与其它矿石相近,并且用同一种流程选别都可获得高质量精矿。但是,由于矿石具有蛇纹石含量增高其可选性恶化的矿物学特征,严重地影响了精矿质量。因此,为了更有效地开采矿床,研究矿石的成分和工艺特征是十分重要的。
Magnetite minerals containing serpentine mineral types are widely developed in the deposits of the Southern Arndan iron ore district in the Soviet Union. Magnetite ores of this type account for almost 50% of the reserves in some deposits, and are still larger in the surface layer of the ore body. The ore is similar in process technology to other ores and high-quality concentrates can be obtained from the same process. However, the mineralogical characteristics of the ore, which have deteriorated their selectivity due to the increased serpentine content, have a serious impact on the quality of the concentrate. Therefore, in order to more effectively mine the ore, it is very important to study the composition and process characteristics of the ore.
