This present paper discusses both the dry and wet magnetic separation techniques used for processing of a low grade siliceous iron ore sample. 2. Materials and methods. About 500 kg of a low grade siliceous iron ore sample was crushed to below 10 mm size by using jaw crusher. The crushed sample was thoroughly mixed and subjected for sampling by
Recent advances in magnetic separator designs and applications M. DOBBINS*, P. DUNN*, and I. SHERRELL* *Outotec (USA) Inc., Minerals Processing, Physical Separation Magnetic separation equipment has long been used to upgrade and beneficiate a wide variety of minerals and materials. Over the years, significant advances in both wet and dry magnetic
The magnetic system is made from high quality ferrite magnetic materials and /or rare earth magnet steel. On the shell surface, the magnet intensity is 100 600mt. The wet type permanent magnet cylindrical separator is commonly used for iron ore separation. It is suitable for
Exceeding the limits of this magnetic loading will result in increased magnetite losses. There are two distinct applications for wet drum magnetic separators. One application is the recovery of magnetite or ferrosilicon in a heavy media process. The other is the concentration and recovery of
Wet Drums for Concentration Duty. Wet drum magnetic separators are the most vital part of the upgrading process in magnetite concentration. The upgrading of primary magnetite is always accomplished with wet drum separators. Mill feed is typically upgraded to 65+ percent magnetic iron using a series of wet drum magnetic separators.
Oct 04, 2018Magnetic separation can be conducted either in a dry or in a wet environment, although wet systems are more in use. Magnetic separation is a physical separation of discrete particles based on the three way competition between tractive (i) magnetic forces, (ii) gravitational, hydro dynamic drag, frictional, or inertial forces, and (iii) attractive or repulsive inter particle forces.
This series of equipment is mainly aimed at combining the weak magnetic separation and gravity separation, flotation, high intensity magnetic separation of hematite ore, i.e. recovering magnetite by weak magnetic spin, recovering weak magnetic iron minerals by flotation, magnetic separation,parallel process of berkelium burn magnetic separation
The Magnetic Separator is suitable for wet magnetic separation of materials,such as magnetite, calcined ore, etc., and it can remove the iron in the coal, non metal and construction industries. The magnetic system is made from high quality ferrite magnetic materials and /or rare earth magnet steel.
But, there are two classifications of magnetic particles, strongly magnetic particles, such as iron and magnetite, and weakly magnetic particles, such as rutile, ilmenite, and chromite. Strong magnetic particles may be easily separated with a separator having a low intensity magnetic field of 400
They are commonly used to recover / reject magnetite from HMC ahead of high intensity wet or dry magnetic separation. For the wet LIMS there are two models, counter current and co current flow. All LIMS consist of a rotating drum within which a fixed permanent magnet is located.
This dry magnetic separator can separate raw materials with different magnetic rigidities. The magnetic separator has the advantages of simple structure, big processing volume, convenient operation and easy maintenance, etc. Purpose of Magnetic Separator The Magnetic Separator is applicable for wet mineral separation of such materials as magnetite, pyrrhotine, roasted ore and
Wet drum magnetic separators of special design may be used as a magnetic thickener for thickening purpose of magnetic concentrates, usually at the end of a magnetic separation process, or as a high intensity magnetic separator, for the removal of very fine ferromagnetic particles and iron corrosions produced in the grinding process of a
Apr 19, 20171.Overview of Mining equipment wet magnetic separator Mining equipment wet magnetic separator is a device which is designed to assist with the purification and and separation of process streams. It is used in industries like mining, and smaller versions are utilized in . Get Price wet type magnetic separator iron ore separation equipment
Product Structure. The non magnetic ores approach the clean surface of drum and the magnetic ores can be absorbed in the strongest magnetic field. Semi counter flow type permanent magnetic drum separator slurry is fed into cavity from the bottom of drum, and the magnetic ores fall into concentrate tank after reaching a certain height,
The range of wet magnetic separators is com posed of the series WS1200 with drum dia meters of 1200 mm with a magnetically effective drum length up to 3678 mm, in increments of 613 mm. Two different tank designs are avail able concurrent and counter rotation. Magnetic separation theory The magnetic separation of magnetite and other
Wet drum magnetic separators are the most vital part of the upgrading process in magnetite concentration. The upgrading of primary magnetite is always accomplished with wet drum separators. Mill feed is typically upgraded to 65+ percent magnetic iron using a series of wet drum magnetic separators. The number of magnetic separation
Wet Low Intensity Magnetic Separators (WLIMS) As the flowrate increases, the slurry velocity and consequently the fluid drag force increases which tends to detach more magnetite particles from the opposing magnetic field. 3. Percent solids. The percent solids of
Application Low Intensity Magnetic Separator (LIMS) Applications. Magnetite Processing Wet drum magnetic separators are used extensively in magnetite processing to recover and upgrade magnetite.. Dense Media Separation Wet drum magnetic separators are used extensively in dense media separation to recover mineral used as a flotation medium i.e. magnetite ferro silicon.
Magnetic separation theory. The magnetic separation of magnetite and other magnetic minerals is a complex process. During the separation process, each particle is subjected to a number of forces, including grav ity, drag, etc. The simplified equation below describes the magnetic force the particles are subjected to
iron ore magnetic separation equipment magnetic separator 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
Wet drum magnetic separators are the most vital part of the upgrading process in magnetite concentration. The upgrading of primary magnetite is always accomplished with wet drum separators. Mill feed is typically upgraded to 65+ percent magnetic iron using a series of wet drum magnetic separators.
