In the present study, the effect as well as optimization study of three process variables such as Magnetic Intensity (Tesla), Pulsation Frequency (per min) and Ring Rpmof the feed material .
· Based on the ore characteristics ( particle size, mineralogy and grade), gravity concentration (jig and Humphreys spiral), magnetic separation (low and highfield) and inverse ionic flotation (especially applied to pellet feeds) are used [3], [4]. It is estimated that for each tonne of beneficiated iron ore, 400 kg of tailings are produced.
· Magnetic separation has two major appliions in mineral processing plants: The removal of tramp iron (which would deleteriously affect subsequent processes) from an ore stream. This is usually achieved by a low intensity magnet suspended above, or at the head of, a conveyor. Separation of magnetic minerals from less magnetic minerals.
· In this research, the efficiency of magnetic separation methods for processing of a lowgrade 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 % The most valuable minerals are Hematite and Goethite and main gangue .

During the study, three different tailings named as low grade, medium grade and high grade with % Fe 3O 4, % Fe 3O 4 and % Fe 3O 4, respectively, were used. Mineralogical analyses ...
This study investigates the effectiveness of magnetic concentration techniques for the beneficiation of borehole samples of Arasuko West Sumatera iron ore. It is a lowgrade type of ore sample (±35% Fe) with high silica and calcium content (±36%). Based on the fact, that there are appreciable differences in magnetic susceptibility between the desired iron minerals and .
Investigation of Efficiency of Magnetic Separation Methods for Processing of LowGrade Iron Pigments Ore (RED Ochre). ... Keywords: Red Ochre, Iron, HighIntensity Magnetic Separation, Full Factorial Design 1. Introduction Red ochre is one of the most important iron oxide forms. The main mineral of red ochre is Hematite (Fe 2O3) and it uses in many industries such as paint, .
magnetic separators and the principal ferromagnetic mineral separated is magnetite (Fe304),although hematite (re203) and siderite (FeCO3) can be roasted to produce magnetite and hence give good separation. The removal of "tramp" iron from ores can also be regarded as a form of lowintensity magnetic separation.
· Magnetic separation is one of the main beneficiation methods of iron ore extraction. This article will analyze 4 key points of operation to teach you how to increase efficiency of iron ore magnetic separation process.
· Iron Ores (Hematite and Magnetite) Iron is a metal from the periodic table''s first transition series and group 8. It is the most common element on Earth by mass, just ahead of oxygen ( % and %, respectively), forming much of the Earth''s outer and inner cores. It is the fourth most abundant element in the crust of the Earth.
