Effects of Multi-stage Grinding Process and Grinding
· Tests on grinding fineness show that the optimal fineness of primary grinding and regrinding in the separation process of multi-stage grinding should be 65 -0.074mm and 90 -0.045mm respectively. The produced iron concentrate can successfully reach 64.28 Fe and 0.42 S respectively with iron recovery of 53.62 and desulfurization rate of

Energy Use of Fine Grinding in Mineral Processing
· Fine grinding to P80 sizes as low as 7 μm is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding it can still account for a substantial part of a mill s energy budget.
