What minerals are required for magnetic separation? Common Iron Minerals are magnetite (strong magnetic minerals), hematite (weak magnetic minerals), Limonite, specularite, siderite (all weak magnetic minerals). They are raw materials for the steel industry. The iron ore grade is low, many impurities. Therefore 80% above iron …

Finally, an iron ore concentrate assaying a Fe grade of 62.12% with a recovery of 56.93% was prepared using wet magnetic separation at a magnetic intensity of 0.5 T from the ore roasted under the ...

The iron recovery increased by 5.77% compared with the results of the conventional magnetic separation. The high efficiency in phosphorus removal and iron recovery achieved by the MFS process may be attributed to the adequate liberation of iron particles and the increase in magnetic force on the iron mineral fines in the form of …

The optimum grade that could be obtained from single-stage dry magnetic separation was 35.52% Mn, and with a Mn:Fe ratio of 1.77, and 44% Mn recovery in the case of sample 1; whereas, a 33.75% Mn grade, with a Mn:Fe ratio of 1.66 at Mn recovery of 44% was reported for Sample 2. It was observed that both samples had a similar input chemistry ...

When implemented correctly, magnetic separation offers an opportunity to recover a variety of valuable minerals residing in host ore. Magnetic susceptibility . Magnetic susceptibility is a measure of how susceptible a mineral is to a magnetic field. The higher the magnetic susceptibility, the stronger the force of attraction to a …

The magnetic moment of the iron ore was as low as 1 emu/g, indicating that iron in the iron ore was hardly extracted by traditional magnetic separation. In RRP-750 °C and RRP-800 °C, magnetic moment increased to ~35 emu/g because hematite in the iron ore was efficiently converted into magnetite combined according to the phase …

The Reading Rare Earth Magnetic Drum (RED) uses a unique 5 pole magnetic element to generate a field intensity in excess of 0.7 Tesla on the drum skin.
