铁磁性颗粒在外磁场的作用下或者由于其本身所具有的剩磁而形成磁链或磁絮团。随着选矿深度的增加必须对矿石进行细磨,这便引起矿粒磁化系数的减小和矫顽力的增大,因而增加了磁絮团的强度,使矿泥和贫连生体混入磁絮团的概率增加,降低了精矿的质量。为了提高湿式磁选过程的效率,建议使用超声频率域的弹性波来预防磁絮团的形成和破坏已形成的絮团。超声波在选矿过程
The ferromagnetic particles form flux chains or magnetic flocs under the action of an external magnetic field or due to their own remanence. With the increase of dressing depth, the ore must be finely ground, which leads to the decrease of magnetization coefficient and coercive force of the ore particles, thus increasing the strength of the magnetic flocs and mixing the slime and lean biomass with magnetic floc The increased probability of mass reduction of concentrate quality. In order to improve the efficiency of the wet magnetic separation process, it is recommended to use elastic waves in the ultrasonic frequency domain to prevent the formation of magnetic flocs and destroy the flocs that have formed.
