Present investigation includes the magnetizing roasting of low-grade iron ore fines followed by grinding and beneficiation using magnetic separation. The hematite iron ore used in the investigation contains 53.17% T Fe, 10.7% SiO2, and 4.5% Al2O3. Powdered bituminous coal of 210 μm size with an ash content of 12.5% and fixed carbon of 54.25% was used as …
Mining magnetic separator is common equipment in mineral processing. And magnetic separation is the main method of iron ore dressing. 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).
The separation technology provides for production of iron ore concentrate with total iron content of 65.9% and recovers 91.0% of magnetite and 80.5% of hematite from the tailings containing 20.4% ...
The principal separation in iron ore beneficiation, therefore, is between the iron minerals, hematite and/or magnetite, and silica, principally in the form of quartz (SiO 2). The use of flotation, either alone or in combination with magnetic separation, has been well established as an efficient method for rejecting silica from these iron ores.
Magnetic separators employ an external applied magnetic field to pull out magnetic materials such as iron ore and ferrous metals.These machines work on the principle of applying magnetic force to pull out fine particles from the feed material. Electrostatic separators, on the other hand, work based on the conductivity of the minerals, whereby electrical fields are …
The magnetic iron content in the calcined ore and magnetic separation concentrate accounted for 96.86% and 97.73%, respectively, while the magnetic iron content in the raw ore was only 4.14%. This indicated a complete transformation of the iron ore phase from Fe 2 O 3 to Fe 3 O 4 after HRR conversion.
Dry permanent magnetic separators have been widely used in the mineral and coal processing industries due to their simple operation and high separation efficiency. These tools not only discard some amount of bulk gangue from the raw ore, thereby reducing the volume of the grinding operation and cutting energy consumption, but also do not require water in the sorting …
The magnetic separation steps between grinding stages progressively reduce the amount of material to be ground and in many cases improve the abrasive properties of the interim concentrates. ... (for the mining industry) established itself as the convention in the comminution of cement, clinker, slag, iron ore, iron ore pellet plant feed and ...

This chapter introduces the principle of how low-grade iron ores are upgraded to high quality iron ore concentrates by magnetic separation. Magnetite is the most magnetic of all the naturally occurring minerals on earth and can be readily extracted by low-intensity magnetic separators from magnetite ores. On the other hand, oxidized iron ores ...
