摘要

该研究介绍了对低品位赤铁矿应用各种选矿方法的结果，赤铁矿最初的特征是含铁量为 17.2% 的粘土岩。研究介绍了原矿石的矿物成分，并考察了不同选矿技术的效果，包括跳汰、磁选（添加添加剂焙烧后）和浮选。结果表明，最简单的方法，即跳汰法，能显著提高精矿中的铁含量，使总铁含量达到 50%。然而，这一结果在很大程度上受到矿石中赤铁矿夹杂物大小的影响。通过其他选矿方法进一步精炼，可使精矿中的总铁含量达到 60%。

Application of various methods of benefication to low-grade hematite ore

The study presents findings on the application of various beneficiation methods to low-grade hematite ores, originally characterized as a clay rock with an iron content of 17.2%. The study presents the mineralogical composition of the original ore and examines the effectiveness of different beneficiation techniques, including jigging, magnetic separation (after roasting with additives), and flotation. The results reveal that the simplest method, jigging, significantly enhances the iron content in the concentrate, achieving a total iron content of 50%. However, this outcome is heavily influenced by the size of hematite inclusions within the ore. Further refinement through additional beneficiation methods allows the total iron content in the concentrate to reach 60%.
