磁铁石英岩的分选工艺是经三至四段破碎至25~15mm，或经一段破碎到350~250mm，通过自磨与球磨(砾磨)结合，实施三段细磨，进入多段磁选。磁铁石英岩选矿的工艺特点是采取阶段磨矿和磁选流程，以便阶段排出单体脉石，减少下一阶段的磨矿量。

The separation process of the magnetite quartz rock is broken up to 25~15mm by three to four, or by means of a broken to 350~250mm, which is carried out by self grinding and ball milling (gravel mill). The three section is fine grinding, and the magnetic separation is entered into a number of magnetic separation. Magnetite quartzite ore dressing process characteristics is to take the stage grinding and magnetic separation process to stage discharge single gangue, reduce the next stage of the grinding capacity.
