Full article: Review of flotation of feldspar

Under these conditions, neither quartz nor feldspar will float unless activated. Following the flotation of mica, titanium and iron oxide minerals may be removed at the same pH using an anionic collector (e.g. a petroleum sulphonate) at a dose rate of about 0·5–2·0 kg t −1. Again, neither quartz nor feldspar will float unless activated.

Froth Floatation - Purdue University

Froth Flotation. After being rinsed, if the sample contains feldspar and mica it will be frothed. To efficiently separate feldspar and mica from quartz, we have developed a procedure that makes feldspar and mica hydrophobic and the quartz becomes hydrophilic. By adding a carbonated solution to the sample, we can separate up to 95% of the feldspar.
