Magnetic Separation and Iron Ore Beneficiation IspatGuru

Oct 04, 2018· Induced roll separators are used to treat weakly magnetic iron bearing ores, while pulley separators are most often used in the removal of tramp iron from various feeds. These separators are using either permanent magnets or electromagnets and operate in a continuous mode.

ADVANCES IN MAGNETIC SEPARATION OF ORES

magnetic separation. Dry Magnetic Separation of Iron Ore: There are many inherent advantages in processes that utilize dry magnetic separation to beneficiate iron ore. Wet concentration of magnetite ore, in comparison, re- quires 500 to 1000 gal of water per ton of concen- trate produced. This means extensive use of water

Magnetic Separators 911Metallurgist

The rare-earth magnetic roll (REMR) magnetic separator has no such air gap. Consequently, the magnetic force does not decline in the manner of an IMR set with a large air gap. Magnetic Separators Application in Mineral Industry. One of the oldest tools used in mineral concentrating is the magnetic separator.

model on magnetic separation of iron ore

Magnetic separation methods are used to take the advantage of the difference in the magnetic properties for separating iron ore from the non-magnetic associated gangue materials. Magnetic separation can be conducted either in a dry or in a wet environment, although .

CHAPTER-8 BENEFICIATION OF IRON ORES

Der Waals, and capillary. A magnetic separator is generally classified as low intensity if its maximum field intensity is less than about 2000 gauss (H= 1.6 x 105 A/m, B=0.20 T).' Low intensity magnetic separators (LIMS) are used to treat ferromagnetic and highly paramagnetic minerals such as iron and magnetite. High intensity magnetic separators

Recent advances in magnetic separator designs and applications

hybrid rare-earth magnetic separator is a cross between rare-earth roll and drum magnetic separator (Figure 5). The FluxForceTM utilizes an ultra thin and flexible shell that comes in direct contact with a smaller diameter magnetic roll, enabling the belt and idling roll assembly to be eliminated. This magnetic roll is similar to those used in the

Magnetic separation Wikipedia

Magnetic separation is the process of separating components of mixtures by using magnets to attract magnetic materials. The process that is used for magnetic separation detaches non-magnetic material with those that are magnetic. This technique is useful for not all, but few minerals such as ferromagnetic (materials strongly affected by magnetic fields) and paramagnetic (materials that are

Separation analysis of dry high intensity induced roll

Sep 01, 2014· A dry induced roll magnetic separator is simple and efficient for upgrading the magnetic mineral and materials. Weak paramagnetic minerals can be effectively removed from an ore by maintaining the field intensity up to ~ 2.5 T,.IRMS as shown in the Fig. 1 consists of a horse-shoe magnet faced by an iron

Iron ore mining and dressing tec-science

In magnetite-containing rock, there is another possibility of separating gangue and iron ore. As the name magnetite already suggests, this type of iron ore is a magnetic rock. This allows the ground ore to pass relatively easily through magnetic separators, where the ferrous rock is separated from the rest of the gangue (magnetic separation).
