A new aspect of magnetic separation, the capture of diamagnetic particles in high gradient magnetic filters, is reported in detail for the first time. it is not generally realized that, in such systems, diamagnetic as well as paramagnetic particles may be captured and that the former undertake capture trajectories causing them to be held at the surfaces of fibres in angular sectors repulsive.
Magnetic separation is most commonly used in the mining industry to separate tramp ore, or unwanted waste metals, from the rest of the bulk material. tramp ore typically consists of the manmade byproducts created by the mining process itself, such as wires from explosive charges, nuts and bolts, nails, broken pieces from hand tools such.

High gradient magnetic separation (hgms) is an effective method for the concentration or removal of paramagnetic particles from various suspensions , and it has been widely applied in the field of mineral processing, for recovery of fine weakly magnetic minerals and for removal of such minerals from nonmetallic ores 2 method is achieved through the use of numerous small magnetic.
In magnetic separation, as the mass and the magnetic susceptibility of the particle are fixed, only the magnetic field intensity or gradient can be varied to change the magnetic force. this is why it is extremely important to create a magnetic field of high intensity and gradient for oxidized iron ores in order to achieve higher iron recovery.

Magnetic separation has been considered for many years a valuable method to achieve the purification of streams of particles (dry or wet) . magnetic separators have unrestricted industrial applications and are widely used in mineral beneficiation, food, textiles, plastic and.
The use of strong magnetic field gradients and high magnetic fields generated by permanent magnets or superconducting coils has found applications in many fields such as mining, solid state chemistry, biochemistry and medical research. lab scale or industrial implementations involve separation of macro and.
For the primary separation, a magnetic separator (typically an induced magnetic roll or rare earth roll separator) removes magneticallysusceptible para and ferro magnetic minerals (e.g. ilmenite, garnet, monazite). the secondary electrostatic separation focuses on separating the remaining minerals (e.g. zircon sand, silica and rutile).
Magnetic filtration has been applied in place of lime treatment by feng and coworkers (2000).ultrafine magnetic particles are used as magnetic seeds. at a dosage of 0.5 gl magnetite, all fine precipitate flocs can be rendered strongly magnetic. the mine water is treated with hydrogen peroxide (to oxidize ferrous iron and manganese), followed by the addition of lime and magnetite to raise the.
