the applicability of beneficiating a low-grade, hematite-magnetite ore (assaying 18.64% Fe) for subsequent uti-lization. In this study, process mineralogy and beneficiation of the ore were carried out in the laboratory. First, mineralogical investigation shows that the main metal minerals are hematite, magnetite and a little octahedrite
