Enhanced kaolinite flotation using amine coated nanobubbles
Kaolinite (Al 2 Si 2 O 5 (OH) 4) is the major mineral phase in kaolin ores and is often found, as gangue mineral, in bauxite and iron ores. Direct and reverse flotation are normally applied to recover kaolinite from kaolin ores and kaolin-washing tailings as well as to remove kaolinite gangue from bauxite and iron ores [1], [2], [3], [4].
