Muscovite exhibits higher negative potentials than biotite, and consequently, the onset of muscovite flotation is found to be at a lower amine concentration than biotite flotation. In the absence of oleate and at 1 10-5 M of amine, nearly 70% of the muscovite is recovered where the biotite recovery is 22.5%.

Exercise 3.4 Porphyritic Minerals. As a magma cools below 1300°C, minerals start to crystallize within it. If that magma is then involved in a volcanic eruption, the rest of the liquid will cool quickly to form a porphyritic texture. The rock will have some relatively large crystals (phenocrysts) of the minerals that crystallized early, and the rest will be very fine …
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 …

1. Introduction. Rapid global industrialization, especially that of high-temperature industries such as steel, has increased the demand for high-end magnesium refractory products and consumption of magnesium-containing minerals [1], [2].Magnesium is the eighth most abundant element in the Earth's crust (with an abundance of ∼2%) …
Figure 1 also shows that muscovite and biotite depress copper and molybdenum flotation in the process of flotation using seawater and that the depressing effect is more relevant at pH 11 than at pH 9.
