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).


These separators also opened the field for magnetic separation of sulphide ores, whose minerals mainly belong to the groups of para- and …


This paper demonstrates simple and cost-effective microfluidic devices for enhanced separation of magnetic particles by using soft magnetic microstructures. By injecting a mixture of iron powder and polydimethylsiloxane (PDMS) into a prefabricated channel, an iron–PDMS microstructure was fabricated next to a microfluidic channel. Placed between two external …

It separates weakly magnetic and paramagnetic particles, such as stainless steel and steel alloys, up to approximately 40 mm. The high-gradient magnet is used after the


Metso Outotec HGMS high gradient magnetic separators are designed to recover weakly magnetic material from non-magnetic matter and can be used for many applications including the processing of iron ores, rare earths and other weakly magnetic minerals, which are not normally treatable by ordinary magnetic separators.


overhand magnet separate coarse FE metal . Product Description for high intensity permanent magnetic FE collecting machine: RCYD strong permanent overband self-discharge magnetic separators adopting the rare earth material NdFeB as the magnetic source, it features with reliable function, unique magnetic circuit, strong magnetic force, and high magnetic gradient.


The magnetic system of the Metso HGMS produces a uniform mag-netic field in the process area. To generate the necessary magnetic field gradient, a matrix of magnetic material with a structure such as expanded metal or steel wool is inserted. A high magnetic field gra-dient is hereby created around the filament of the matrix. The sharp


Drum separators are affected by the amount of magnetics in the slurry. The recovery decreases in dilute slurries — an effect not seen in high gradient separators. Also they are limited to 20% solids or less in the feed and 60-70 gpm/ft of drum width if the non-magnetics content is re- …

Introduction. Drum Magnet is generally placed at the end of the conveyor belt for the separation of scrap steel in most recycling industries, it can also effectively separate the weak magnetic materials from non-magnetics because of its high magnetic intensity.. High Intensity Drum Magnet is suitable for using as a secondary magnetic separator or fine sorting …


Magnetic Head Pulley-Qijin Magnet Co., Ltd.-Magnetic Head Pulley also know as magnetic roller is a reliable solution for the continuous extraction of ferrous metals from a product stream. Magnetic pulley or magnetic roller are installed as a replacement head pulley at the discharge end of a conveyor to separate the ferrous material away from other materials.


In a high gradient type magnetic separator such as the one described here, the competing forces are largely determined by the relative velocities of the particles, slurry and matrix. In the separator described here in the relative velocity between the matrix and the slurry is controllable independent of the average through-put velocity of the ...

The HGMS is often indiscreetly referred to as WHIMS (wet high intensity magnetic separator). However there are a lot of differences, which places the Metso HGMS in a separate category: • Unlike to the WHIMS, HGMS is capable of handling and recovering particles down to extremely fine sizes due to the possibility to choose a suitable matrix grade with large collection area and …


using a high-gradient magnetic field. The research that Dr. Finlayson and I conducted sought to utilize a wire mesh or "steel wool" to create high local gradients in an otherwise homogenous field to collect the As-magnetite particles in a cycle that would alternate between the separation of the particles and cleaning the filtration device.
