What Affect the Magnetic Effect of Magnetic Separator?

The major factor which influences the separating effect of magnetic separator is the particle size of feeding materials. For most ores, the feed size marks the separation of ore monomer size, which is the particle separation degree of magnetic mineral particles and the gangue particles. If the particle size of feeding ore is small, that means the single mineral separation degree is high, which can obtain satisfactory separation indexes; if the feeding ore particle size is coarse, it illustrates that the mineral is not fully dissociated and the monomer separation degree is not high. On the contrary, intergrowth also has a magnetic, the sorting of a considerable part can pick up the grade of concentrate.

The slurry concentration is one of the main factors affect the magnetic separation effect of magnetic separator, which mainly refers to the size of overflow concentration. If the slurry concentration is too large, it will result in high concentration, so it will seriously affect the quality of concentrate. Because the concentrate particles are easily covered by finer gangue and the sorting of particle coverage and parcel is not open, with the election to lower grades. The slurry concentration is too small that separation concentration is too low, it will cause the increase in flow velocity shortened separation, so that some tiny magnetic particles which have a chance should be up will enter into the grade of tailings, since the tailings increased, it will cause the loss. Therefore, the pulp concentration needs to be adjusted according to the need. The adjustment in the separator mainly relies on the adjustment of the ore size; however, most of the process is completed by the classification of overflow density, which must be based on the magnetic separation requirements. The slurry concentration has a maximum limit of 35%, which is generally controlled in about 30%. It needs to determine the specific amount according to the actual situations.
