Low-grade iron ore received from the West Singhbhum area of Jharkhand state in India was used to develop a beneficiation flow sheet to remove alumina (Al2O3) and silica (SiO2) from the ore to get iron (Fe)-rich product for steel plants. Mineral characterization showed that the main mineral constituents present in the head sample …

In this paper, a sample from Tange-zagh iron mine was characterized by gravity and magnetic separation methods. The mineralogical studies showed that hematite and goethite are the main iron-bearing minerals with insignificant amounts of FeO. The results indicated that spiral separation yields higher separation efficiency than …

Jigging is especially useful for low-grade iron ores, potentially creating saleable product from what would otherwise be mine waste. For example, Sishen Mine in South Africa has shown that lower-grade ROM (50–60% Fe) can be upgraded to a saleable 64% Fe product, greatly enhancing the resource base of the mine (Pretorius and Hoffmann, 2006).
