在矿石准备过程中,现有的磁选工艺表明,磨矿具有重大作用。磨矿段最终产品粒度由要求矿物的单体解离度确定,在这种情况下,经过磁选可得到计划的铁品位。第一段磨矿操作判据可用一次联立方程式表示: In the ore preparation process, the existing magnetic separation process shows that grinding has a significant effect. The particle size of the final product in the grinding section is determined by the degree of monomer dissociation required for the mineral, in which case the planned iron grade is obtained by magnetic separation. The first grinding operation criterion can be expressed as a simultaneous equation:
