15/05/2019· In this research, the efficiency of magnetic separation methods for processing of a low-grade iron pigments ore (red ochre) has been studied. Based on the mineralogical analyses (XRD), thin section and polish studies, the reserve is an iron sedimentary deposit with an average Fe grade of %31.3. The most valuable minerals are Hematite and Goethite and main gangue minerals are Calcite and Quartz.

Iron Ore, Hematite, Magnetic Separation, Reverse Floatation, Multi-Stage Process 1. Introduction The increase in demand for iron in the steelmaking industries and the depleting high-grade iron ores has led to the alternative extraction of iron from hematite based low-grade ores [1]. The low-grade iron ores contain higher grades of silica How to cite this paper: Haga, K., Siame, M.C. and

04/10/2018· Magnetic separator separates the iron ore feed material into two or more components. If the purpose is to produce a magnetic concentrated iron ore then the other component which is non-magnetic is the tailings. In some cases there can also be a possibility of separating the less magnetic third component which is called middlings. Each of these material streams are to be transported into, through the separator, or out of the separator.
