The dry magnetic separator is used for sorting dry magnetic minerals, and is mainly used for selecting large-sized, coarse-grained ferromagnetic ores and fine-grained weak magnetic ores. It has three types of single disc (diameter φ = 900 mm), double disc (φ = 576 mm) and three discs (φ = 600 mm). The magnetic field strength can reach 880-1440 kA/m.

A magnetic separator to select must be suitable for the purpose of use and have a sufficient capacity. To select such a most suitable separator, when ... Then foreign matters like iron are removed by a magnet. Materials screened to various sizes become products as recycled crushed stone and recycled sand.
Figure 2: Images of samples after magnetic separation. The non magnetic fraction is essentially pure quartz. (a) Magnetic (top) and non magnetic (bottom) fraction of four sand samples. (b) …
"Wet low intensity magnetic separation has been used for the recovery of magnetite for decades. As high-grade reserves continue to decline, low grade magnetite ores are being targeted for iron production. Low grade magnetite mineralisation is typically fine grained and requires fine to ultrafine grinding (P80 40 - 30 µm) to liberate it from, predominantly, …
Magnetic separators can be found in most mineral processing operations, especially those processing non-metallic minerals and magnetic ores. This article investigates the use of high intensity magnetic separators and magnetic separation equipment in the minerals sector with a focus on processing dry materials (in the -15mm, +45 micron size range).
Magnetic separation technology plays a pivotal role in mineral processing, offering efficient and versatile solutions for separating valuable minerals from gangue materials. By harnessing the magnetic properties of …
Acomparative analysis is made of magnetic separators used to decrease and stabilize the iron content in quartz sand. It is shown that obsolete electromagnetic roll and rotor separators are cumbersome, unreliable, and expensive to operate. The construction of belt roll separators using permanent magnets has a number of irremovable defects that impede the …
Magnetic separator is a general term for equipment that uses magnetic force to separate magnetic substances from non-magnetic substances. They play a very important role in the beneficiation process. Most magnetic separators are used for ore selection, such as quartz sand, garnet, pyrite, hematite, limonite, siderite, etc.
Ceramic producers turned to technology, with magnetic separators and screens, to identify and then remove problematic minerals and fine iron. Many ceramic raw material deposits, such as feldspar, silica sand, ball clay and kaolin, have problematic magnetic minerals including micas (muscovite and biotite), hematite, chromite, and iron stained quartz.
The magnetic separator is a crucial apparatus used in the magnetic separation process [13]. ... Typically, iron-based soft magnetic materials like pure iron, mild steel, and ferritic permeable stainless steel are used, with ferritic permeable stainless steel being the most commonly used.
Slurry magnetic separator is a common equipment in lab magnetic separation test and is often used to purify and remove impurities from quartz, feldspar, kaolin and other non-metallic minerals. It is mainly used to …

The excess amount of Fe is removed using an external magnet wrapped in a butter-paper, the excess Fe powder chokes the feeder of the magnetic separator, therefore must be removed. After this treatment the feldspar start behaving like a magnetic mineral and get …
Magnetic separators can be found in most mineral processing operations, especially those processing non-metallic minerals and magnetic ores. This article investigates the use of high intensity magnetic separators …
Introduction. Pulsating high gradient magnetic separation (PHGMS) is now widely applied in the world, for separation of fine weakly magnetic ores such as oxidized iron ores, ilmenite and wolframite and for purification of non-metallic ores such as quartz and feldspar, due to its high reliability, high throughput and low operational cost [1], [2].The highest …
a wide variety of magnetic separators for use with lump materials, granular materials, clay-like materials and liquids. A magnetic separator to select must be suitable for the purpose of use and have a sufficient capacity. To select such a most suitable separator, when inquiring about separators, conditions such as the purpose of use and
The non magnetic fraction is essentially pure quartz. (a) Magnetic (top) and non magnetic (bottom) fraction of four sand samples. (b) Close up of sample before magnetic separation. Note abundant quartz, feldspar (pale, opaque) and some heavy mineral grains (125-150 µm). (c) Close up of the non-magnetic fraction.
According to the XRD data, the ore contains minerals of 38.2% quartz, 35.5% albite, 25% microcline and 1.3% mica. The dry high-intensity magnetic separator model MIH (13) 111-5 is depicted in It was used to remove titanium and iron from the feldspar concentrate product produced under the optimum flotation conditions that was mentioned previously.
The magnetic separation process can remove weak magnetic impurities such as hematite, limonite and biotite. Strong magnetic separation usually uses a wet magnetic separator or a high gradient magnetic …
