Quartz, feldspar and mica are some of the most abundant minerals in the earth's crust. Quartz (SiO2) is present in almost all rocks. It is hard, resistant to chemical weathering and has no cleavage, which means it is also resistant to physical weathering. It is abundant in silica-rich igneous rocks, like granite and rhyolite.

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.
