muscovite from quartz. The results revealed that neither muscovite nor quartz is floated with NaOl alone, and while using DDA alone, the minerals can be separated only under strongly acidic conditions (pH < 3). However, mixed NaOl/DDA collectors exhibit an excellent performance in the flotation separation of muscovite from quartz at pH 10.

The results reveal that the separation of muscovite from quartz is feasible at strong acid pulp condition using amine collectors. TTA and DTAC show poorer collecting ability for flotation of the two minerals compared with DDA. Physical adsorption is found to be the main adsorption module of amine collectors on muscovite and quartz by FT-IR ...

Conversely, the mineral is readily recovered using cationic collectors, such as amines. At pH values greater than 5, many silicates are negatively charged. This means that selective separation of muscovite mica from these minerals, using a cationic collector, may not be possible (Nakazawa et al., 1988).

Muscovite is the primary vanadium-bearing mineral in stone coal because the V 3+ substitutes the Al 3+ from the dioctahedral structure as an isomorphism in muscovite [2,3]. Due to the low vanadium grade, …

A common effective recovery method for muscovite is flotation, which achieves consolidation of muscovite mineral particles within froth and separation of associated gangue minerals (feldspar and quartz) into tailings [11], [12], [13].Thus, the selection of the flotation reagents is critical for its flotation efficiency.
