Abstract
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%.
