When materials run below separator, iron contamination hidden in material will be attracted on the working surface of separator. 2、Move the Permanent Magnetic Separator away from belt conveyor when separator has attracted a certain amount of iron, and remove iron on separator with non-magnetic tools. Separator can continue to work after cleaning.
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. In some cases there can also be a possibility of separating the less magnetic third component which is called middlings. …

gradient magnetic separation (PHGMS) would greatly reduce the entrainment effect and can obviously increase the grade of the magnetic product. It is also very helpful for reducing the clogging of the matrix [27, 28]. In the present investigation, a typical Iranian low grade iron ore sample collected from Tange-zagh mine was considered.
As shown in Figure 13.2, minerals with ferromagnetic properties have high susceptibility at low applied field strengths and can therefore be concentrated in low intensity (<~0.3 T) magnetic separators. For low-intensity drum separators (Figure 13.11) used in the iron ore industry, the standard field, for a separator with ferrite-based magnets, is 0.12 T at …
