US6098810A Flotation process for separating silica from

A separation process is provided for treating a feed material comprising silica, feldspar, and metal impurities, including at least one of mica, iron impurities, or refractory heavy minerals, to form one or more products for use in making glass. In the process, the feed material is floated in the presence of a depressant to inhibit the flotation of feldspar and thereby form a concentrate

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 flotation[29].
