Re-election and magnetic separation equipment for magnetite iron

The re-election method for iron ore, mainly for the selection of magnetic iron ore, the application of two: a mineral grade higher grade (50%), but the ore body is thinner or sandwich, mining waste rock mixed, so that the ore depleted, the ore can be used only broken and not grinding, in the case of coarse, through the re-election discard coarse tailings, thereby recovering the geological grade. Get coarse grain of medium grade concentrate, or further processing, or directly to the blast furnace smelting, this is called coarse-grained re-election. The other is on the embedded grain size of the red ore or mixed ore (that is, containing weak magnetic red ore and ferromagnetic magnetite), by crushing, grinding iron ore monomer separation, by re-election or magnetic re-election, fine-grained high-grade concentrate, which is called fine-grained re-election.

Magnetite magnetic separation process often used in the mineral processing equipment are mainly crushing equipment, grading equipment, grinding equipment, sorting equipment, transportation equipment and transportation equipment, magnetic separator in the magnetite magnetic separation process (Such as ferrosilicon, maghemite, pyrrhotite) into the magnetic field of the magnetic separator, along the magnetic field orientation to form a magnetic chain Or a magnetic beam. The demagnetization factor of the fine flux is much smaller than that of the individual particles, and its magnetic susceptibility or magnetic induction is much higher than that of the individual particles. The magnetic flux formed in the magnetic field of the magnetic separator has a good effect on the recovery of fine magnetic particles, especially when wetting. This is because the magnetic susceptibility of the flux is higher than the magnetic susceptibility of a single magnetic particle, and the resistance of the water medium to the flux is relatively upward in the direction of the magnetic field, but on the contrary, it is less than the resistance of the individual particles.
