Mica Beneficiation
Acid Cationic Flotation Method. The acid cationic method of mica flotation provides an efficient method for recovery of coarse mica. Particles as coarse as 14 mesh may be floated by the process. However, the ore must be completely deslimed at 150 to 200 mesh, which results in considerable loss of fine mica.
