Flotation of mica minerals and selectivity between muscovite and

Selective flotation of muscovite from a material containing muscovite (15.4%), biotite (13%), and siliceous gangue (quartz and feldspar), using a mixed collector system of sodium oleate and dodecylamine acetate has been described. Muscovite is found to float in preference to biotite, when the pulp is initially conditioned with oleate followed by amine at basic pH values. …

Separation of lepidolite from hard-rock pegmatite ore via dry

The lepidolite and muscovite were separated to obtain a Li pre-concentrate assaying 3.5 % Li 2 O from a feed grade containing 1.8 % Li 2 O. Nevertheless, according to the zeta-potential measurements, the flotation test performed with the finer-sized fraction (–210 + 63 μm) showed that lepidolite flotation was optimised between pH 3 and 5.
