CHEMICAL PROPERTIES OF THE MINERAL MICA Chemical Composition: The general formula for mica group minerals is XY Z O (OH, F) : X: Can be K, Na, Ba, Ca, Cs, (HO), or (NH). Y: Includes Al, Mg, Fe, Li, Cr, Mn, V, and Zn. Z: Comprises Si, Al, Fe, Be, and Ti. The chemical properties of mica minerals vary depending on the specific type of mica. However, all micas are silica (SiO2), aluminum oxide (Al2O3), and potassium oxide (K2O). Some micas may contain other elements, such as iron oxide (Fe2O3) and magnesium oxide (MgO). The following table shows the chemical composition of some common mica minerals: Mica mineral SiO2 Al2O3 K2O Fe2O3 MgO Muscovite 45.57 33.1 9.87 0 0 Biotite 47.7 30.9 3 10 3 Phlogopite 47.5 31 3 0 15 Of the 28 known species of mica, six are common rock-forming minerals: Muscovite: The common light-colored mica. Biotite: Typically black or nearly black. Phlogopite: Typically brown. Paragonite: Macroscopically indistinguishable from muscovite. Lepidolite: Generally pinkish to lilac; occurs in lithium-bearing pegmatites. Glauconite: A green species found sporadically in marine sedimentary sequences.

1. PARTICLE SIZE: The proportion of fragments with particle size under 8 Mesh not be more than 8% 2. IMPURITIES: The proportion of impurities (biotite quartz stone and sand etc.) will not more than 2% 3. CALCINATION: The Mica Flakes will withstand calcination temperature of 850-920 temperature degree centigrade for 30 minutes. The calcined material will turn to silver/white colour.
