电磁液体静力分选是在不均匀强磁场中,以顺磁性盐类的水溶液为介质,不同的矿物由于比重、磁化系数的差异,在介质中具有不同的悬浮高度,以适当的方法分别提取,可获得两种或两种以上的产品。其分选原理,简述如下。 在磁极间隙中,放入一只分选槽(槽的形状与磁极间隙的空间一致),槽内装有分选介质——顺磁性液体。将一颗体积很小的矿粒放入槽中,当矿粒在介质中悬浮(满足静力平衡条件)时,如不考虑磁场在X与Z方向的梯度变化,则有下式(图1):
Electromagnetic hydrostatic separation is in a non-uniform magnetic field to paramagnetic salt aqueous solution as a medium, different minerals due to specific gravity, magnetic susceptibility differences in the medium with different suspension height, respectively, by appropriate methods were extracted , You get two or more products. The sorting principle, summarized as follows. In the pole gap, into a sorting tank (groove shape and space of the pole gap space), the tank is equipped with sorting medium - paramagnetic liquid. A small volume of ore particles into the tank, when the mineral particles suspended in the medium (to meet the static equilibrium conditions), if not consider the gradient of the magnetic field in the X and Z direction, then the following formula (Figure 1 ):
