目前所采用的选别克里沃罗格矿区和库尔斯克磁力异常区细粒浸染的磁铁石英岩的工艺流程主要由三段磨矿分级,2～3段磁力脱泥,4～5湿式磁选组成。这样的工艺流程可保证在最终磨矿粒度为94～98%—74μm(90～94%—50μm粒级)条件下获得品位63
The current selection of Kerry Voronog mine and Kursk magnetic anomaly zone finely grained magnetite quartz rock process consists of three sections of grinding grading, 2 to 3 sections of magnetic desliming, 4 to 5 wet magnetic separation composition. Such a process ensures that the final grinding grade is 94-98% -74μm (90-94% -50μm grain size) grade 63
