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.
