Maximizing the recovery of fine iron ore using magnetic separation Most iron ore operations that require beneficiation of ROM ore to produce lump, fine (sinter), and pelletizing concentrate iron ore products will discard a slimes fraction to final tailings. This fraction can vary in particle size from –200 µm down to –10 µm.

Applications include heavy minerals, ilmenite, manganese and iron ore (haematite) beneficiation; PGM upgrading as well as manganese recovery from slimes dams. This offers new approaches and technology for solving para-magnetic minerals separation processes that are as efficient as they are cost-effective.

separation is used to enrich iron ore samples that demonstrate either para- or ferromagnetic behavior (Flippov et al. 2014). Magnetic separation can be performed on wet or dry material, with wet being a slurry (Flippov et al. 2014). Magnetic separators are broken down into two categories: high and low intensity (Flippov et al. 2014).

The quality of Indian iron ore resources is generally good with high iron content and high percentage of lumpy ore. More than 85% of the hematite ore reserves are of medium- to high-grade (+62% Fe) and are directly used in blast furnace and in direct-reduced iron (DRI) plants in the form of sized lump ore, agglomerated sinter, and agglomerated pellets (Iron and …

Magnetic Separation; Principle: This method is used when either the ore or the impurities are magnetic in nature; Example: Concentration of Iron Ore using Magnetic Separation: Iron ore is magnetic, while the gangue particles are non-magnetic. A magnet is used to separate the magnetic particles from the non-magnetic ones.

The magnetic separation method is one of the most effective and easiest methods of getting the iron ore from the other materials. This technique is very useful in high throughput operations where large volumes of slurry are …

Fig. 2 illustrates the iron ore beneficiation process, particularly magnetic separation, resulting in the generation of inevitable tailings. Due to the characteristics of iron ores and the conditions during beneficiation, it is inevitable that approximately 2.5–3 tons of IOTs are generated for every 1 ton of iron ore concentrate produced [7].In 2019, the global annual …

Conventional magnetic separation is to separate minerals according to their natural magnetism. In addition, in some cases, in order to improve the efficiency of separation, it is possible to change the magnetism of minerals or take some special methods to make the mineral separation more effective, such as magnetization roasting and magnetic separation, magnetic …

Sensor-based ore sorting can be used as a separation process for coarser grain sizes before the application of fine comminution and separation technologies and is applicable for a large variety of mineral raw materials. ... gold, copper, iron ore, chromite, diamonds, phosphate, and limestone processing. Development efforts have been invested in ...

Iron ore tailings containing around 48–60% Fe are generated from the iron ore washing plants and are disposed into tailing ponds without any further utility. These tailings in the form of slimes are not suitable in iron and steel making due to the presence of higher amount of gangue constituents. ... The detailed separation principle of ...
