WebFeb 4, 2024 · As the pH increased, the flotation yield showed an increasing trend (Figure 1b), but a high flotation yield does not necessarily reflect the effective separation of quartz and biotite. Because the quartz and biotite both floated at pH 5.5 and 6.5, it seems difficult to separate only F-containing mica minerals from the soil. Biotite is a common group of phyllosilicate minerals within the mica group, with the approximate chemical formula K(Mg,Fe)3AlSi3O10(F,OH)2.
