ADVANCES IN MAGNETIC SEPARATION OF ORES

Magnetic separation is also important in process- ing phosphate, titanium, chrome, manganese, tung- sten, molybdenum, nickel, niobium, and tantalum ores. Pioneer Work on Dry Separation: It is interesting to note that much of the pioneer work in magnetic processing of ores was done on dry material.

Dual intensity magnetic separation process for beneficiation ...

The use of conventional magnetic separators to remove ferromagnetic minerals is known. Magnetic separation is an important process that has been used in mineral dressing for many years. Most metallic ores are crushed and the values are concentrated using flotation, gravity settling, electrostatic separation, or other special processes.

The gangue may be the magnetic material in certain cases. Iron ores and manganese ores are the main ones for which we use magnetic separation. Magnetite and Chromitite ores (both iron ores) use this method on a large scale to remove their impurities. Learn the process of extracting Crude Metal from Concentrated Ore.

Mineral processing - Concentration | Britannica

Mineral processing - Mineral processing - Concentration: Concentration involves the separation of valuable minerals from the other raw materials received from the grinding mill. In large-scale operations this is accomplished by taking advantage of the different properties of the minerals to be separated. These properties can be colour (optical sorting), density (gravity separation), magnetic ...

The density of chromite ore is slightly higher than that of its other magnetic gangue ore. Therefore, the separation of ferrochromium from other minerals can be realized by gravity separation. Use spiral chute to separate the concentrate process tailings and the scavenging process concentrate respectively.

Electromagnetic separation: If the mineral and not gangue is attracted by a magnet, it can be concentrated by magnetic separation. For example, chromite ore, being magnetic can be separated from non-magnetic silicons impurities by this method. Sometimes two minerals occur together, in which one happens to be magnetic.

Magnetic Separation and Iron Ore Beneficiation IspatGuru

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.

Which of the following ores cannot be concentrated by ...

For example, iron ores are attracted towards the magnet, hence, nonmagnetic impurities can be separated from them using magnetic separation. Here, Haematite, Magnetite, and Sidderite are iron ores and hence magnetic separation can be used to separate them. Malachite is a Copper ore and hence magnetic separation can't be used to concentrate it.
