Multotec Australia s range of magnetic separators for mineral processing is comprehensive and consists of as well as recovering fine particles as small as 15 µm The magnetic recovery options are flexible and are therefore used in both wet and dry slurries with the range incorporating oil cooled electromagnets that increase equipment
4 Magnetic separator is the basic tool used by mineral processing plants to separate ferrous and non ferrous metals from extracted ore ensuring high quality final products Its works by attracting magnetic particles such as iron steel and nickel and then using powerful magnets or electromagnets to separate these particles from other materials
Applications of SLon magnetic separators in Chinese oxidized iron ore processing industry are introduced in the paper Discover the world s research 25 million members
4 Magnetic separators Adjustment of magnet and drum position The position of magnetic drum and the angle of the magnetic assembly can easily be adjusted to obtain the best process perfor mance The adjustment possibilities include • Magnet assembly positioning in relation to the concentrate dis charge weir • Horizontal position of the drum
Understanding Magnetic Separation Magnetic separation leverages the magnetic properties of minerals to separate magnetic materials from non magnetic ones This process is particularly effective for iron removal from mineral mixtures making it a cornerstone technique in the mining and mineral processing industries Types of Magnetic Separators 1
As shown in Figure minerals with ferromagnetic properties have high susceptibility at low applied field strengths and can therefore be concentrated in low intensity < T magnetic separators For low intensity drum separators Figure used in the iron ore industry the standard field for a separator with ferrite based magnets is T at a distance of 50 mm from
The development of wet high intensity magnetic separators WHIMS and wet high gradient magnetic separators HGMS with a matrix in a ring of magnets Jones 1960;Yang et al 2018 have enabled
Magnetic separators are renowned for their separation of magnetic ore; they can also serve as an electromagnet effective for removing tramp metals providing the ideal solution for magnetic separation in mineral processing These are the reasons why Multotec s magnetic separators are used in mineral processing plants worldwide
The used concrete is crushed into small pieces to be reused to make new concrete Magnetic separators are used to remove metal reinforcing structures found within the used concrete These ferrous impurities not only affect production rate but also product purity Therefore the use of magnetic separators becomes critical
The most extensively magnetic based separators in mineral processing engineering are magnetic drums Drum magnets are mainly manufactured based on permanent magnets However the Permos separator which uses small magnet blocks in its structure Dry magnetic separation of iron ore of the bakchar deposit Procedia Chem 15 160 166
In mineral processing magnetic separation can be carried out either at low intensity high intensity or high gradient The Low Intensity Magnetic Separators LIMS are suitable for minerals having strong magnetic susceptibility while High Intensity Magnetic Separators HIMS is a preferred choice for minerals with weak magnetic susceptibility
A DISCUSSION OF MAGNETIC SEPARATION TECHNIQUES 197 Introduction Minerals separation based on magnetic susceptibility differences in particles is accomplished wet or dry at various intensities and in different basic machine configurations The following types of industrial magnetic separators can be found in a modern mineral sands plant
The lines of force from the magnet are concentrated upon the points of the armature giving a strong field capable of attracting weakly magnetic minerals The magnetic attraction is strongest at a point on the horizontal diameter of the armature and steadily decreases from this point around to the vertical diameter
4 Rare earth drum magnetic separator for fine feed dry magnetic separation sorting process and rare earth roller magnetic separator for zircon and rutile in heavy mineral sand industry These magnetic separators have different applications and the dry magnetic separator is also moving toward large scale and easy to manufacture
Generally dry or wet low intensity magnetic separators are used for ferromagnetic minerals whereas high intensity magnetic separators are widely used for paramagnetic mineral separation Dwari et al 2013 Magnetic gravity and hydrodynamic drag forces are the major forces that control the overall reaction of particles in the magnetic field
3 Graphite ore beneficiation includes gravity separation flotation and magnetic and electric separation; it is widely used in separating natural graphite flake graphite crystalline graphite graphite in granite According to the specific composition and properties of the ore JXSC will combine multiple methods for comprehensive processing to achieve the best
4 Rare earth drum magnetic separator for fine feed dry magnetic separation sorting process and rare earth roller magnetic separator for zircon and rutile in heavy mineral sand industry These magnetic separators have different applications and the dry magnetic separator is also moving toward large scale and easy to manufacture
to high intensity induced roll magnetic separators which remove feebly magnetic minerals Generally about 25 pct of the ore fed to a nephe line syenite plant is lost as waste during crushing drying grinding and reduction of iron content which is usually lowered from to pct Table
