Summary of Fluorite Ore Flotation Process - JXSC Machine
The ground ore of a coarse size indicates that may have many associated fluorite ore lumps, these lumps may increase the silica content, decrease the flotation effect. If the grinding particle size is too fine, although quartz and fluorite have been dissociated from the monomer, it will cause the fluorite losing easily, thus reduce the recovery ...
