本文对遵义碳酸锰矿的物质组成进行了详尽的介绍。阐明了矿石中的矿物组成、结构构造、嵌布特征,锰、铁之间的关系以及在空间上的变化规律。通过对各种矿物物理参数的测定,揭示了矿物间的主要差异是比磁化系数,据此,进行了分级磁选试验。研究结果指出:在该区矿石中,不仅碳酸盐类矿物与脉石矿物存在磁性差异,而且在碳酸锰类质同象系列中,随着Mn、Fe、Ca含量的变化,其磁性也各不相同。采用磁力分析仪分级磁析表明,能抛弃大量脉石,达到脱泥降铁之目的。得到的锰精矿再次磁选,可以进一步抛弃高铁、高钙碳酸锰,得到更为纯净的锰精矿。因此作者认为磁选处理该类矿石有广阔的前景。
This article describes the material composition of Zunyi manganese carbonate in detail. The mineral composition, structural structure, embedded features, the relationship between manganese and iron in ore and the change rules in space are clarified. Through the determination of various mineral physical parameters, it is revealed that the main difference between the minerals is the specific magnetization coefficient, and accordingly, the hierarchical magnetic separation test is carried out. The results show that there are not only magnetic differences between carbonate minerals and gangue minerals in the ore of this area, but also their magnetic properties vary with the content of Mn, Fe and Ca in the manganese carbonate isomorphism series the same. Grading magnetic analysis using magnetic analysis shows that a large number of gangue can be discarded to reach the purpose of desliming iron. The resulting manganese concentrate magnetic separation again, you can further abandon high-speed rail, high-calcium manganese carbonate, get more pure manganese concentrate. Therefore, the authors believe that magnetic separation of ore processing has broad prospects.
