The weak magnetic separation process is often added before the strong magnetic separation process to separate the strong magnetic minerals in the ore in case that the strong magnetic minerals may cause the blockage of the magnetic separator. After the weak magnetic separation, the strong magnetic rough separation and sweep selection are carried ...
1.2 If 70% of the iron is recovered to the spiral concentrate at a grade of 66.4% Fe, what is the concentrate grade and iron recovery to the magnetic concentrate? 1.3 What is the iron content of the spiral tailing? where Sc = Spiral concentrate S = Spiral tailings Mr: Magnetic separator feed MT: Magnetic separator tails MC: Magnetic separator ...
ABSTRACT: Present investigation includes the magnetizing roasting of low-grade iron ore fines followed by grinding and beneficiation using magnetic separation. The …
This Laboratory Magnetic Separator is a high intensity dry device which uses a rotating iron disc to concentrate the magnetic field and remove the magnetic particles from the non-magnetic. It essentially consists of an electromagnet (the applied current is controlled by a rheostat) which produces a magnetic field across the air gap and a belt ...
A tin-bearing iron concentrate with an iron content of 64.36 wt.% was obtained first, while the tin content was as high as 0.253 wt.%. Then the effect of roasting parameters on the separation of tin was investigated, and the results were shown in Fig. 8 and Table 3.

The application relates to a magnetic separator for refined iron powder, which belongs to the technical field of magnetic separators and comprises a separator, wherein a roller is rotatably connected to the inner wall of the separator, a first magnet which does not rotate along with the roller is arranged in the roller, a raw material box is arranged on one side of the separator, …
In a superconducting magnetic separator, a high field intensity over 5 T is generated by a superconducting magnet system (Watson, 1994), ... and the sediment was fed to the magnetic separator to produce a iron concentrate (magnetic product) and a middling (non-magnetic product). Actually, in this procedure, the centerpiece is the FMS process.
For each cDMS experiment in this investigation, the magnetite-quartz mixture was fed to the full-scale cDMS-1000 separator at 1.2 t/h. When all the cDMS experiments were finished, the iron grades of magnetite in magnetic products (concentrate) and non-magnetic products (tailings) were weighed and assayed.
Magnetic Seperation - Download as a PDF or view online for free ... # Since 19th century magnetic separation processes have been used to concentrate and separate minerals. ... For the concentration of iron ore other than magnetite, after preliminary conversion of iron minerals to artificial magnetite by suitable Roasting.
Lastly, another low intensity magnetic separation step on the obtained magnetite concentrate was applied to produce the final iron concentrate. The obtained iron concentrate reaches 64.28% Fe and ...
Working Principle When the ore pulp entering magnetic field area, the ferromagnetic materials are sucked up on the surface of the drum, weak magnetic substance and nonmagnetic minerals are washed away by water, the absorbed magnetic minerals on the surface of drum are rotated with the drum and taken out of magnetic field area .The rotary one is suitable to dry …
Iron ore magnetite processing (LIMS, MIMS, WHIMS, Davis Tubes) The increased worldwide demand for steel in recent decades has led to an increase in the exploitation of magnetite iron ore deposits as an alternative to hematite DSO ores. Magnetite concentrate is a higher-grade product than hematite and very desirable as a smelter feed.
Magnetic separator separates the iron ore feed material into two or more components. If the purpose is to produce a magnetic concentrated iron ore then the other component which is non-magnetic is the tailings. ... The …
And successfully recovered the iron concentrate through magnetic separation. The suitable transformation conditions were 700 ℃, 30 min, and 30 % of CO content. The optimal conditions for grinding and magnetic separation were −37 μm content 92.42 % and 143.35 kA·m −1, respectively. Under these conditions, the iron grade and recovery of ...

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 ...
Wet Permanent Magnetic Drum separator is a kind of magnetic separator often used in iron ore concentrators. It is suitable for separating high magnetic minerals. According to the different structure of the tank, it can be divided into three types: downstream type, counter-current type, and semi-counter-current type. ... The semi-countercurrent ...
The ground sample was subjected to different finer sizes and separated by wet low intensity magnetic separator. It was possible to obtain a magnetic concentrate of 67% Fe by recovering 90% of iron values at below 200 lm size. Ó 2013 Published by Elsevier B.V. on behalf of China University of Mining & Technology. 1.
After each experiment, the total iron and magnetite iron grades of magnetic (concentrate) and non-magnetic (tailings) products produced from the cDMS separator were assayed. The separation performance of the cDMS separator was evaluated on the basis of the mass weight and quality of concentrate, and its total iron and magnetite iron recoveries.
