silica flotation cationic

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 attributed to the more negatively charged surfaces of silica [5].

Cationic flotation of silica from magnetic iron ore

Twelve cationic, amine-salt silica-collectors were evaluated on three samples of magnetic iron-ore concentrate. Coco primary amine acetate was used as the standard of comparison. Lauryl primary amine acetate is somewhat more efficient in collecting silica than the standard, and equally selective. Tallow primary amine acetate is equally selective and somewhat less efficient than the the ... Learn More
