found that the flotation behavior of kaolinite is opposite to that of silica. For example, ether diamine, a st rong collector for silica, does not induce any flotation of kaolinite at pH 10. The pH dependence of kaolinite flotation is also opposite to that of silica, which explains why it is difficult to remove kaolinite in iron ore flotation29.
