Beneficiation Methods For Removing Mica From Quartz Sand

The flotation method is mainly used in the recovery of crushed mica and fine-grained mica in the sand and gravel industry, especially the mica resources in the tailings. In actual production and application, the preliminary process flow should be determined according to the nature and characteristics of the actual ore.
