Mica is a mineral name given to a group of minerals that are physically and chemically similar. They are all silicate minerals, known as sheet silicates because they form in distinct layers. Micas are fairly light and relatively soft, and the sheets and flakes of mica are flexible. Mica is heat-resistant and does not conduct electricity.

Abstract. The batch flotation response of mica in dodecylamine solution was related to film experiments where the stability, thickness, and interfacial potentials at the air/dodecylamine solution interface was determined. These results were compared with surface force data (reported in an earlier publication) in which hydrophobic adhesion ...
5. Flotation Separation. We carry out the separation according to the difference in the physical and chemical properties of the mica and quartz sand surfaces. Crush the quartz ore and ground to dissociate the mica monomer. Under the action of the mineral dressing agent, the mica becomes a product and separates from the gangue.
