In mineral processing, magnetic separation is used to separate iron-bearing minerals from non-ferrous minerals, such as quartz, feldspar, and mica. Other commonly used applications include iron ore beneficiation, industrial minerals, and coal processing. Let's look at each of these:

We would like to show you a description here but the site won't allow us.

As shown in Figure 13.2, minerals with ferromagnetic properties have high susceptibility at low applied field strengths and can therefore be concentrated in low intensity (<~0.3 T) magnetic separators. For low-intensity drum separators (Figure 13.11) used in the iron ore industry, the standard field, for a separator with ferrite-based magnets, is 0.12 T at a …

 — Introduction. Hematite (α-Fe 2 O 3) is widely distributed in various rocks and is one of the most common and abundant iron oxide minerals in soil (Zhang, 2007).However, it cannot be used in iron and steel industry without preliminary beneficiation due to its low grade. Many researchers have investigated the separation of iron minerals …

 — 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, so low-intensity magnetic separators are used to upgrade magnetite ores.

 — For improving selectivity of HGMS in processing refractory weakly magnetic minerals, we developed a novel method termed high gradient magnetic separation coupling with magnetic fluid (HGMSCMF) and experiments on the refractory ilmenite ore (serious competing capture occurred between ilmenite and titanaugite) in Panzhihua in Sichuan …

 — By harnessing the magnetic properties of minerals, magnetic separators can selectively capture and concentrate target minerals based on their magnetic susceptibility, facilitating high-purity separation and enhancing the overall efficiency of mineral processing operations. ... Iron ore is perhaps the most well-known example of a mineral that is ...

 — Magnetic separator is the basic tool used by mineral processing plants to separate ferrous and non-ferrous metals from extracted ore, ensuring high-quality final products. Its works by attracting magnetic particles such as iron, steel and nickel, and then using powerful magnets or electromagnets to separate these particles from other materials.

 — In the present investigation, magnetic separation studies using an induced roll magnetic separator were conducted to beneficiate low-grade ferruginous manganese ore. The feed ore was assayed to contain 22.4% Mn and 35.9% SiO2, with a manganese-to-iron mass ratio (Mn:Fe ratio) of 1.6. This ore was characterized in detail using different …

 — What that means in practice depends on the extraction style. If the mineral is paramagnetic – like iron or cobalt – chances are that it's processed using magnetic separation. The mineral is first crushed then funnelled past an electromagnet, the precious material sucked away to safety and the waste product left down below.

 — Dry magnetic separation is a technology that sorts magnetic minerals from gangue using air as the medium instead of water. When raw ore is fed to the magnetic …

The comprehensive iron concentrate grade is 65% and the recovery rate reaches to 93.86%. In the Sierra Leone project, 22 sets SLon-2500 Iron Ore HGMS have been introduced. With the same processing techniques, …

 — The lean iron ore magnetic separator performs rough separation after coarse or medium crushing to remove waste rocks such as surrounding rocks, improve the grade, and reduce the load of the following process. ... However, Some highly magnetic minerals cannot be sorted, which limits their scope of use. It is especially suitable for sorting ...
