Mechanism of separating muscovite and quartz by flotation

Flotation experiments were performed to investigate the separation of muscovite and quartz in the presence of dodecylamine (DDA), tallow amine (TTA) and dodecyltrimethylammonium bromide (DTAC). The adsorption mechanisms of these three kinds of amines on muscovite and quartz were studied by FTIR spectrum analysis, contact angle measurement and molecular dynamics (MD) simulation.
