Reverse Cationic Flotation Of Silica And Silicates

For the reverse flotation process, silica was floated using cationic surfactants in a weak acidic or neutral pH, and the phosphate minerals dominantly apatite were obtained from the underflow product. The superior adsorption of cationic surfactants on silica rather than apatite probably can be
