Background technology
Magnetic separation is a kind of simply and effectively material processing method, can avoid the medicament pollution of chemical treatment method and the drawback of high cost.Because the iron ore grade of China is low, impurity content is high, must separate through the multistage magnetic separation to obtain qualified iron-smelting raw material.For the ferromagnetism ore, adopt low-intensity (magnetic) separator can effectively obtain high-grade iron ore concentrate, if but needing to obtain the iron grade is higher than 67% iron ore concentrate, just must adopt the picking equipment of column magnetic separator one class.
Permanent-magnet drum type magnetic separator is the most general low-intensity (magnetic) separator that adopt in domestic and international ore dressing plant, but because this equipment sorting interval is limited, magnetic coagulation can't fully disperse, and causes the increase rate of concentrate grade limited, has also limited to a certain extent as blast furnace fine fodder is provided.
The selected at present main electromagnetic field column magnetic separator that adopts of magnetic iron ore, it is a kind of picking equipment based on magnetic field force, gravity and ascending water impulse force, magnetic mineral is magnetized in the magnetic field in the sorting cylinder, form magnetic and roll into a ball downward sedimentation, the weak zone in magnetic field, magnetic group is opened by ascending current, and gangue mineral wherein is cleaned out, discharge from top, concentrate is discharged from the bottom.Although column magnetic separator iron concentrate grade can be increased to 69% in addition higher more than, but still have following problem:
(1) water consumption is bigger than normal, per tonly needs 2 to 4 tons of waters to the ore deposit;
(2) stricter to the feed preparation unit size requirement, the suitable feed preparation unit size of general column magnetic separator is 0.2mm;
(3) tailings grade of column magnetic separator is higher, and a part is poor, rich intergrowth is easy to along with gangue enters mine tailing, causes mine tailing to be still needed because grade is higher and continues to process.
The Rotating field magnetic separator that is seen at present report also is the equipment that utilizes magnetic field force, gravity, ascending water impulse force to carry out sorting, mainly rotating the change in polarity that produces by magnetic system makes magnetic group that magnetic rolling occur, under the effect of toroidal magnetic field, the magnetic ore particle is magnetized, reunion, sedimentation, thereby the gangue that makes wherein parcel is developed by ascending water and discharge from top and to become mine tailing, and magnetic mineral is settled down to the bottom and becomes concentrate.Compare with column magnetic separator, owing to do not possess clear superiority, cause this equipment not to be successfully applied to production.
Studies show that, behind primary grinding, being contained in the above magnetic iron ore of 30% in the ore occurs with the monomer dissociation state, present magnetic plant can't be realized function that this part magnetic iron ore is separated in advance, therefore the compound force field magnetic plant of development of new meets high efficiente callback, energy-saving and cost-reducing mining development trend.
